Jean le Flambeur gets up in the morning and has to kill himself before his other self can kill him first. Just another day in the Dilemma Prison. Rescued by the mysterious Mieli and her flirtatious spacecraft, Jean is taken to the Oubliette, the Moving City of Mars, where time is a currency, memories are treasures, and a moon-turned-singularity lights the night. Meanwhile, investigator Isidore Beautrelet, called in to investigate the murder of a chocolatier, finds himself on the trail of an arch-criminal, a man named le Flambeur....

Indeed, in his many lives, the entity called Jean le Flambeur has been a thief, a confidence artist, a posthuman mind-burglar, and more. His origins are shrouded in mystery, but his deeds are known throughout the Heterarchy, from breaking into the vast Zeusbrains of the Inner System to stealing rare Earth antiques from the aristocrats of Mars. In his last exploit, he managed the supreme feat of hiding the truth about himself from the one person in the solar system hardest to hide from: himself. Now he has the chance to regain himself in all his power—in exchange for finishing the one heist he never quite managed.

Hannu Rajaniemi's The Quantum Thief is a breathtaking joyride through the solar system several centuries hence, a world of marching cities, ubiquitous public-key encryption, people who communicate via shared memory, and a race of hyper-advanced humans who originated as an MMORPG guild. But for all its wonders, The Quantum Thief is also a story powered by very human motives of betrayal, jealousy, and revenge. It is a stunning debut.

As always, before the warmind and I shoot each other, I try to make small talk.

'Prisons are always the same, don't you think?'

I don't even know if it can hear me. It has no visible auditory organs, just eyes, human eyes, hundreds of them, in the ends of stalks that radiate from its body like some exotic fruit. It hovers on the other side of the glowing line that separates our cells. The huge silver Colt would look ridiculous in the grip of its twiglike manipulator limbs if it hadn't already shot me with it fourteen thousand times.

'Prisons are like airports used to be on Earth. No one wants to be here. No one really lives here. We're just passing through.'

Today, the Prison's walls are glass. There is a sun far above, almost like the real one but not quite right, paler. Millions of glass-walled, glass-floored cells stretch to infinity around me. The light filters through the transparent surfaces and makes rainbow colours on the floor. Apart from them, my cell is bare, and so am I: birth-naked, except for the gun. Sometimes, when you win, they let you change the little things. The warmind has been successful. It has zero-g flowers floating in its cell, red and purple and green bulbs growing out of bubbles of water, like cartoon versions of itself. Narcissistic bastard.

'If we had toilets, the doors would open inwards. Nothing ever changes.'

All right, so I am starting to run out of material.

The warmind raises its weapon slowly. A ripple passes through its eyestalks. I wish it had a face: the stare of its moist forest of orbs is unnerving. Never mind. It's going to work this time. I tilt the gun upwards slightly, my body language and wrist movement suggesting the motion I would make if I was going to put up my gun. My every muscle screams cooperation. Come on. Fall for it. Honest. This time, we are going to be friends

A fiery wink: the black pupil of its gun, flashing. My trigger finger jerks. There are two thunderclaps. And a bullet in my head.

You never get used to the feeling of hot metal, entering your skull and exiting through the back of your head. It's simulated in glorious detail. A burning train through your forehead, a warm spray of blood and brain on your shoulders and back, the sudden chill – and finally, the black, when things stop. The Archons of the Dilemma Prison want you to feel it. It's educational.

The Prison is all about education. And game theory: the mathematics of rational decision-making. When you are an immortal mind like the Archons, you have time to be obsessed with such things. And it is just like the Sobornost – the upload collective that rules the Inner Solar System – to put them in charge of their prisons.

We play the same game over and over again, in different forms. An archetypal game beloved by economists and mathematicians. Sometimes it's chicken: we are racers on an endless highway, driving at each other at high speeds, deciding whether or not to turn away at the last minute. Sometimes we are soldiers trapped in trench warfare, facing each other across no-man's-land. And sometimes they go back to basics and make us prisoners – old-fashioned prisoners, questioned by hard-eyed men – who have to choose between betrayal and the code of silence. Guns are the flavour of today. I'm not looking forward to tomorrow.

I snap back to life like a rubber band, blinking. There is a discontinuity in my mind, a rough edge. The Archons change your neural makeup a little bit every time you come back. They claim that eventually Darwin's whetstone will hone any prisoner into a rehabilitated cooperator.

If they shoot and I don't, I'm screwed. If we both shoot, it hurts a little. If we cooperate, it's Christmas for both of us. Except that there is always an incentive to pull the trigger. The theory is that as we meet again and again, cooperative behaviour will emerge.

A few million rounds more and I'll be a Boy Scout.


My score after the last game is an ache in my bones. The warmind and I both defected. Two games to go, in this round. Not enough. Damn it.

You capture territory by playing against your neighbours. If, at the end of each round, your score is higher than that of your neighbours, you win, and are rewarded with duplicates of yourself that replace – and erase – the losers around you. I'm not doing very well today – two double defections so far, both with the warmind – and if I don't turn this around, it's oblivion for real.

I weigh my options. Two of the squares around mine – left and back – contain copies of the warmind. The one on the right has a woman in it: when I turn to face it, the wall between us vanishes, replaced by the blue line of death.

Her cell is as bare as mine. She is sitting in the middle, hugging her knees, wrapped in a black toga-like garment. I look at her curiously: I haven't seen her before. She has a deeply tanned skin that makes me think of Oort, an almond Asian face and a compact, powerful body. I smile at her and wave. She ignores me. Apparently, the Prison thinks that counts as mutual cooperation: I feel my point score go up a little, warm like a shot of whisky. The glass wall is back between us. Well, that was easy. But still not enough against the warmind.

'Hey, loser,' someone says. 'She's not interested. Better options around.'

There is another me in the remaining cell. He is wearing a white tennis shirt, shorts and oversized mirrorshades, lounging in a deck chair by a swimming pool. He has a book in his lap: Le Bouchon de cristal. One of my favorites, too.

'It got you again,' he says, not bothering to look up. 'Again. What is that, three times in a row now? You should know by now that it always goes for tit-for-tat.'

'I almost got it this time.'

'That whole false memory of cooperation thing is a good idea,' he says. 'Except, you know, it will never work. The warminds have non-standard occipital lobes, non-sequential dorsal stream. You can't fool it with visual illusions. Too bad the Archons don't give points for effort.'

I blink.

'Wait a minute. How do you know that, but I don't?'

'Did you think you are the only le Flambeur in here? I've been around. Anyway, you need ten more points to beat it, so get over here and let me help you out.'

'Rub it in, smartass.' I walk to the blue line, taking my first relieved breath of this round. He gets up as well, pulling his sleek automatic from beneath the book.

I point a forefinger at him. 'Boom boom,' I say. 'I cooperate.'

'Very funny,' he says and raises his gun, grinning.

My double reflection in his shades looks small and naked.

'Hey. Hey. We're in this together, right?' And this is me thinking I had a sense of humor.

'Gamblers and high rollers, isn't that who we are?'

Something clicks. Compelling smile, elaborate cell, putting me at ease, reminding me of myself but somehow not quite right—

'Oh fuck.'

Every prison has its rumours and monsters and this place is no different. I heard this one from a zoku renegade I cooperated with for a while: the legend of the anomaly. The All-Defector. The thing that never cooperates and gets away with it. It found a glitch in the system so that it always appears as you. And if you can't trust yourself, who can you trust?

'Oh yes,' says the All-Defector, and pulls the trigger.

At least it's not the warmind, I think when the bright thunder comes.

And then things stop making sense.

In the dream, Mieli is eating a peach, on Venus. The flesh is sweet and juicy, slightly bitter. It mingles with Sydän's taste in a delicious way.

'You bastard', she says, breathing heavily.

They are in a q-dot bubble fourteen klicks above the Cleopatra Crater, a little pocket of humanity, sweat and sex on a rough precipice of Maxwell Montes. Sulphuric acid winds roar outside. The amber light of the cloud cover filtering through the adamantine pseudomatter shell makes Sydän's skin run copper. Her palm fits the contours of Mieli's mons Veneris exactly, resting just above her still moist sex. Soft wings flutter lazily in her belly.

'What did I do?'

'Lots of things. Is that what they taught you in the guberniya?'

Sydän smiles her pixie smile, little crow's feet in the corners of her eyes. 'It's kind of been a while for me, actually,' she says.

'My ass.'

'What about it? It's very nice.'

The fingers of Sydän's free hand trace the silvery lines of the butterfly tattoo on Mieli's chest.

'Don't do that,' Mieli says. Suddenly, she feels cold.

Sydän pulls her hand away and touches Mieli's cheek.

'What's wrong?'

All the flesh of the fruit is gone, and only the stone remains. She holds it in her mouth before spitting it out, a rough little thing, surface engraved with memory.

'You are not really here. You're not real. Just here to keep me sane, in the Prison.'

'Is it working?'

Mieli pulls her close, kissing her neck, tasting sweat. 'Not really. I don't want to leave.'

'You were always the strong one,' Sydän says. She caresses Mieli's hair. 'It is almost time.'

Mieli clings onto her, the familiar feel of her body. The jewelled serpent on Sydän's leg presses hard against her.

Mieli. The pellegrini's voice in her head is like a cold wind.

'Just a little while longer—'


The transition is hard and painful, like biting down on the peach-stone, the hard kernel of reality almost cracking her teeth. A prison cell, fake, pale sunlight. A glass wall, and beyond it, two thieves, talking.

The mission. Long months of preparation and execution. Suddenly, she is wide awake, the plan running through her head.

It was a mistake to give you that memory, says the pellegrini in her head. It is almost too late. Now let me out: it is getting cramped in here.

Mieli spits the peach-stone at the glass wall. It shatters like ice.

First, time slows down.

The bullet is an ice-cream headache, burrowing into my skull. I am falling, yet not falling, suspended. The All-Defector is a frozen statue beyond the blue line, still holding his gun.

The glass wall to my right shatters. The shards float around me, glinting in the sun, a galaxy of glass.

The woman from the cell walks up to me briskly. There is a deliberation in her step that makes it look like something she has rehearsed for a long time, like an actor who has received a cue.

She looks at me, up and down. She has short-cropped dark hair, and a scar on her left cheekbone: just a line of black against her deep tan, precise and geometrical. Her eyes are pale green. 'It's your lucky day,' she says. 'There is something for you to steal.' She offers me her hand.

The bullet headache intensifies. There are patterns in the glass galaxy around us, almost like a familiar face—

I smile. Of course. It is a dying dream. Some glitch in the system: it's just taking a while. Broken prison. Toilet doors. Nothing ever changes.

'No,' I say.

The dream-woman blinks.

'I am Jean le Flambeur,' I say. 'I steal what I choose, when I choose. And I will leave this place when I choose, not a second before. As a matter of fact, I quite like it here—' The pain makes the world go white, and I can no longer see. I start laughing.

Somewhere in my dream, someone laughs with me. My Jean, says another voice, so familiar. Oh yes. We'll take this one.

A hand made from glass brushes my cheek, just as my simulated brain finally decides it is time to die.

Mieli holds the dead thief in her arms: he weighs nothing. The pellegrini is flowing into the Prison from the peach-stone, like a heat ripple. She coalesces into a tall woman in a white dress, diamonds around her neck, hair carefully arranged in auburn waves, young and old at the same time.

That feels better, she says. There is not enough room inside your head. She stretches her arms luxuriously. Now, let's get you out of here, before my brother's children notice. I have things to do here.

Mieli feels borrowed strength growing within her, and leaps into the air. They rise up higher and higher, air rushing past, and for a moment she feels like she lived in Grandmother Brihane's house and had wings again. Soon, the Prison is a grid of tiny squares beneath them. The squares change colour, like pixels, forming infinitely complex patterns of cooperation and defection, like pictures—

Just before Mieli and the thief pass through the sky, the Prison becomes the pellegrini's smiling face.

Dying is like walking across a

desert, thinking about stealing. The boy is lying in the hot sand with the sun beating down on his back, watching the robot on the edge of the solar panel fields. The robot looks like a camouflage-coloured crab, a plastic toy: but there are valuable things inside it, and One-Eyed Ijja will pay well for them. And perhaps, just perhaps Tafalkayt will call him son again if he is like a man of the family—

I never wanted to die in a

prison, a dirty place of concrete and metal and bitter stale smells and beatings. The young man's split lip aches. He is reading a book about a man who is like a god. A man who can do anything he wants, who steals the secrets of kings and emperors, who laughs at rules, who can change his face, who only has to reach out his hand to take diamonds and women. A man with the name of a flower.

I hate it so much when they catch you.

pull him up from the sand, roughly. The soldier backhands him across his face, and then the others raise their rifles—

not at all as much fun as

stealing from a mind made of diamond. The god of thieves hides inside thinking dust threaded together by quantum entanglements. He tells the diamond mind lies until it believes he is one of its thoughts and lets him in. up—

The people who are many have made worlds that shine and glitter, as if just for him, and he just has to reach out his hand and pick them up

It's like dying. And getting out is like

a key turning in a lock. The metal bars slide aside. A goddess walks in and tells him he is free.

being born.

The pages of the book turn.

Deep breath. Everything hurts. The scale of things is wrong. I cover my eyes with vast hands. Lightning flashes at the touch. Muscles are a network of steel cables. Mucus in my nose. A hole in my stomach, burning, churning.

Focus. I make the sensory noise into a rock, like those on Argyre Planitia, large and clumsy and smooth. In my mind, I lie down on a fine mesh, pouring through it, crumbling into fine red sand, falling through. The rock cannot follow.

Suddenly it is quiet again. I listen to my pulse. There is something impossibly regular about it: every beat like a tick of a perfect mechanism.

Faint scent of flowers. Air currents tickling the hairs of my forearms, and other places – I am still naked. Weightlessness. The inaudible but palpable presence of smartmatter, all around. And another human being, not far away.

Something tickles my nose. I brush it aside and open my eyes. A white butterfly flutters away, into bright light.

I blink. I'm aboard a ship, an Oortian spidership by the looks of it, in a cylindrical space perhaps ten metres long, five in diameter. The walls are transparent, the dirty hue of comet ice. There are strange tribal sculptures suspended inside them, like runic characters. Spherical bonsai trees and many-angled zero-g furniture float along the central axis of the cylinder. There is starry darkness beyond the walls. And small white butterflies, everywhere.

My rescuer floats nearby. I smile at her.

'Young lady,' I say. 'I believe you are the most beautiful thing I have ever seen.' My voice sounds distant, but mine. I wonder if they got my face right.

Up close, she looks awfully young, genuinely so: her clear green eyes lack that rejuvenated, seen-it-all look. She wears the same simple garment as in the Prison. She floats in a deceptively comfortable angle, smooth bare legs outstretched, relaxed but ready, like a martial artist. A chain made from multicoloured jewels snakes around her left ankle and up her leg.

'Congratulations, thief,' she says. Her voice is low and controlled, but betrays a hint of contempt. 'You have escaped.'

'I hope so. For all I know this could be some new Dilemma variation. The Archons have been pretty consistent so far, but you are not paranoid if they really have you imprisoned in a virtual hell.'

Something stirs between my legs and banishes at least some of my doubts.

'Sorry. It's been a while,' I say, studying my erection with detached interest.

'Evidently,' she says, frowning. There is an odd expression on her face, a mixture of disgust and arousal: I realise she must be listening to this body's biot feed, a part of her feeling what I'm feeling. Another jailer, then.

'Trust me, you are out. It required considerable expense. Of course, there are still several million of you in the Prison, so consider yourself lucky.'

I grab one of the handles of the central axis and move behind a bonsai tree, covering my nudity like Adam. A cloud of butterflies alights from the foliage. The exertion feels strange as well: the muscles of my new body are still waking up.

'Young lady, I have a name.' I offer her my hand across the bonsai tree. She takes it, dubiously, and squeezes. I return the grip as hard as I can. Her expression does not change. 'Jean le Flambeur, at your service. Although you are absolutely right.' I hold up her ankle chain. It squirms in my cupped hand as if alive, a jewelled serpent. 'I am a thief.'

This was a pretty great book with a lot of interesting concepts. It was so full of new ideas that often there wasnt enough time to explore all the implications of the ideas fully New and interesting author who takes science fiction to the limit. Often the new vocabulary takes some time to internalize, but once done was a pretty great read. Definitely worth trying

I'm in neither in the "My god; it's brilliant!" or the "It's too complicated to read/too brilliant for me to comprehend." camp. Briefly, and under the bling, which is considerable, it's a fairly straightforward story of a man who is valuable to someone very powerful, who therefore springs him from prison, using an unwilling cat's paw to do the job and also ride herd on him. However, before the project for which he was freed can go forth, the prisoner must return to his old stomping grounds and recover his memory. Shenanigans ensue; a mystery is solved; and the set-up for the next book is put into place. The characters are understated, but perfectly comprehensible and sympathetic. I found the thief to be annoying, but not unbearably so. Yes, the author uses made-up words and doesn't explain them; it's not really a problem, doesn't impede the story, and I can't imagine that an adult reader of science fiction would be put off by the vocabulary. So, not a bad read; I'm not sorry I read it, and I would recommend it to readers of science fiction.

This book is good, but can be frustrating for a while. You are not really given any explanation for the first 100 pgs or so, just thrown in and have to learn...however i think, after finishing, that this helps the reader identify with the main character more (he is just as confused for a while and cant remember some important stuff) I did not give it a full five stars because for me, i wanted to keep reading, but also wanted to be done because i could be frustrating. Im sure i missed a ton. Great book though...def worth a read...good start to a trillogy.

It took some time, but in the end I thoroughly enjoyed this book. The first third can be difficult because of the amount of unexplained vocabulary, but once you get the terms down (or at least the gist of it) it's pretty much straight forward from there. There are also some online dictionaries to help as well, which I highly recommend. Since this is going to be a trilogy, I'll forgive the author for the complex foundation, but would have likes a few explanations here and there; which is what kept me from giving it five stars. I loved the concepts, the technology, the structure and the story line. Also, I appreciated how the author didn't give too much depth to the characters. Some hard sci-fi novels work better this way. If you have an open mind and some patience, this is well worth the read.

Easy read, but utterly confusing. Too many neologisms for comfort. I guess a second read would help unlock much of the story's potential
TheDivineOomba on LibraryThing More than 1 year ago
A fun who done it set on a future mars that I almost understood, but didn't quite. By that, I mean you got thrown into this world, without much of an explanation. So the technology is so far advanced, I didn't quite grasp it. But, the characters were entirely human, if augmented a bit. Here, we have a hot shot thief in prison who unexpectedly gets freed by someone who needs his skills. What she needs him to do is not entirely explained, because before the thief can help, he needs to regain his memories that he hid to keep safe. Then, there is the detective, the only person in this world with the skills necessary to solve a series of crimes, stealing someone's gogol, or soul. Leaving the body lifeless an unresurectable. The two plots intertwine on Mars, in an odd moving city where people are determined to be private, and a simple newspaper article can be illegal.The story moved quickly, the plot was well designed and the characters very likeable.Very good first story. I can't wait to read the next in this series.
Dadbrazelton on LibraryThing More than 1 year ago
This book is set in a future that has no connection to our lifestyle. Realistic? Probably, but very difficult to read and enjoy. I quit half way through. The front cover says it is his first Sci-fi novel. Science fiction connects to our lives. This book is therefore fantasy and I do not enjoy fantasy.
SunnySD on LibraryThing More than 1 year ago
Imprisoned thief Jean le Flambeur is broken out of a truly unique prison by Mieli and her amorphously mathematical spidership Perhonen. He's given a new task - steal himself... Sound convoluted? It should, because it is.Highly intellectual, beautifully written, intriguingly plotted - but I couldn't finish this one. Time, memory, mathematics, fractals, aliens, recycled memories, intrigue and societies based on incredibly structured, highly refined manners and mores, violence and regimentation, beauty and privacy... just didn't hook me, though.

Others have already written much better reviews, so I'll keep mine brief.I enjoyed this - it was great fun, with a frantic pace and some great characters. If you've not read much post-singularity hard-sf, then you may find yourself hitting a bit of a barrier with some of the terminology and concepts; the author just assumes you're familiar with the potential implications of ubiquitous nanotech, post-scarcity economies, quantum entanglement and the like and moves on from there.The (gushing) praise on the jacket from Charles Stross compares Rajaniemi's writing with Greg Egan, Ted Chiang and Alastair Reynolds. If you've read and enjoyed Alastair Reynolds then you'll love this - conversely, if you enjoy this and haven't read any Alastair Reynolds, you probably should. (Of course you should read Greg Egan and Ted Chiang too, but to me this felt much more like AR than either of those.)I look forward to the sequel, and other works exploring this universe.

When I've had too much coffee by brain starts spinning out and I can't get to sleep: thoughts belt around like I'm watching five films simultaneously, all on fast forward. Nothing stays in focus for long, but thoughts - some profound, some funny, some scary and some downright weird ricochet off each other like superheated pool balls - often, I've thought, illustrating Chomsky's famously unintelligible sentence "colourless green ideas sleep furiously". The wife calls it my buzzy brain phase. Why do I tell you this? Because reading The Quantum Thief is a bit like having buzzy brain, or at any rate being hotwired into someone else's, and listening to it through a blanket. Hannu Rajaniemi is fiercely intelligent (I read somewhere he's an actual quantum physicist) and he has some powerful ideas. But from the outset, you're expected already to be familiar with them (game theory and the prisoner's dilemma starts, without exposition, on page 1), and then to be nimble enough to follow Rajaniemi's fictional assemblages without any real help from the author. True, he's thereby refraining insulting his readers' intelligence, but at the same time parading his own, and I dare say it is only the most energetic, talented or disingenuous reader who claims to keep up. Many do. One thing to draw from these confections: this isn't hard sci-fi, no matter how many name-checks there may be to Robert Axelrod or nanotechnolegy. I suspect Rajuaniemi is throwing round concepts and hoping they stick, and readers are blustered into pretending they do. Personally I don't think hannu's impish ingenuity - and there is plenty of it, to be sure, is nearly enough to carry the day. I don't think he defies conventional narrative archetypes so much as is completely ignorant of them: Billy Sheehan once said, you have to know the rules before you can break 'em. This is a poorly plotted novel - there are far too many characters, significant ones are under-explained, and the characterisation is wafer thin across the board. Science Fiction can do one of two things: either present a plausible alternative universe based on credibly worked out science (or alternative science) - this is "hard sci fi"; a spod's paradise, but has at least the merit of theoretical integrity - or it can function as a metaphor for an exploration of recognisably human dilemmas (as, for example, Philip K Dick's extraordinary body of work did). Or, optimally, both. The Quantum Thief is neither: the "science" is way too airily thrown about (and under-explained) and the narrative is so confusing (and the baloney science too intrusive) for the story to have significant resonance as a morality tale. What's left - all that's left, I think - is a buzzy brain. Now my own buzzy brain is exasperating enough; having a ringside seat at someone else's is a mite more than this koala can bear.

Jean is an exceptionally good thief. At the beginning of The Quantum Thief, he is rescued from a particularly nasty prison by someone who needs his skills. Isidore is an amateur detective, whom we meet as he solves a case. Of course, this novel will bring these two together, in a complex plot, made more complex by Jean¿s partial amnesia.However, The Quantum Thief is not only a mystery, but science fiction, set in a post-Singularity solar system. Human minds run as software on artificial substrates, possibly as many simultaneous copies, wearing bodies varied in shape and capability. Minds far beyond human intelligence exist. Humanity has splintered into subcultures that might as well be different species; one subculture runs what amount to LAN parties as religious rituals. Jean¿s prison is virtual, confronting many copies of himself and other prisoners with an endless round of prisoner¿s dilemma games, which always eventually end in death for the losing copies. Minds enslaved to carry out work are called gogols, dead souls, whose plight is feared and, in some places, forbidden, so that other means to do the work must be found.The novel is a mystery, dense with clues, revelations and double-crosses, where what Jean¿s rescuer wants him to steal is a larger mystery to them both than how; the story is largely Jean¿s rediscovery of his earlier life. That life, and most of the plot, are set on an attractive, partly terraformed Mars, a relative backwater in the solar system, where gogol slavery has been replaced by periodic stretches of community service by minds who are free the rest of the time. Time away from such service is the Martian currency. Society is mediated by a software network called gevolut, which gives citizens fine, almost fractal control over who has access to information about themselves, in what contexts and for how long. Gevulot is like Facebook would be, had it been designed by some guardian angel of privacy, but universal and ubiquitous. It is this system that Isidore must negotiate, in his first chapters, in order to catch a - well, not killer, exactly, because the victim can be revived, after a fashion. The workings of Mars and gevulot were the most interesting parts of the book for me. Rajaniemi seems very up to date on speculations about mind uploading, online privacy, and the singularity.By contrast, he is weaker on physical science, with much of the exposition on such subjects feeling as though he were asking the reader ¿do you want quantum sauce on that?¿ Other flaws include using standard SF tropes without definition, e.g. ¿utility fog¿ - routine for me, but a reader unused to SF would find the going very rocky. I¿m not sure all the many moving parts of the plot really fit together. Revelations about Rajaniemi¿s solar system are held until late in the book, often for no real plot purpose, making reading the book harder than it needed to be.This is Rajaniemi¿s first novel, and has received a great deal of hype. The Charles Stross blurbs on the cover compare him to Greg Egan, Alastair Reynolds and Ted Chiang. I disagree in the Egan case - he¿s not that interesting on physics and philosophy, Egan¿s specialties, and I also disagree in the Chiang case - he¿s not nearly Chiang¿s equal as a writer. Reynolds - perhaps; I haven¿t read that much Reynolds. Most mysteries are not to my taste, and I found the book overly busy. Rananiemi comes up with a great many clever ideas, many more than I¿ve noted here, but except for the intriguing gevulot material, these ideas felt to me as though nothing but cleverness was really at stake - unlike Stross or Bruce Sterling, for example, where cleverness serves an original, interesting take on the world. The book¿s story has a real ending, but with a coda promising further adventures, so perhaps the second and third books of the promised trilogy will take us further into the more cosmopolitan parts of the author¿s solar system, and fulf

The imagination + understanding how math and quantum work. Kudos

A story set within the complex otherness that is quantum space. You never can fully know how what goes off in this brilliant work about the never dull, seldom understood uncertainties so rampant within quantum space. The best thing about thr story is its engaging dialogue anfd fanciful storyline that pits a master thief against a seasoned detective. What might go wrong does so with deft adherence to uncertainty, improbable as that may sound. Homage is paid to many including the first family of hot air manned balloon flight, and the latest in sentient space vessels. Add in a few more problematic, probabilistic entities and the like, and you have the thief whose stock in trade is dealing with the monetary value of horologic constructs. A uniquely fascinating read, if you can suspend your disbelief that what can go wrong, will do so with only a slight degree repidation at the mere thought of this conundrum. Suffice it to say, the cat is probably the most fanciful of characters, survivor of Schroedinger's box, and who barely makes it into the book, maybe...A fun read with a highly probable uncertainty about what the prison really is. And that is just the start of the improbable uncertainties! The detective aspect of the story is probably its least uncertain aspect, and it is definitely at half of the reality ou can see and believe.

Wonderfully mystery novel set in a hyper technological future. Like Zelazny in Lord of Light, the reader is dragged into the byzantine milieu of the solar system some centuries hence. We are anchored by the familiar humanity of relationships, murder, and greed as the protagonist literally discovers himself as the plot is unwound.

Quantum Thief is a fun if at times dense read with a good mix of action, sci-fi and intrigue. LOTS of complex terminolgy and physis references, so be prepared to do some lookups or daze out through descriptions of technology. Far enough in the future to feel more science fantasy than hard science fiction, but fun nonetheless. Will probably be reading the sequel.
