She’s felt it before…the fear of losing control. And it’s happening again.

In the near future, an aggressive and terrifying new form of dementia is affecting victims of all ages. The cause is unknown, and the symptoms are disturbing. Dr. Gillian Ryan is on the cutting edge of research and desperately determined to find a cure. She’s already lost her husband to the disease, and now her young daughter is slowly succumbing as well. After losing her funding, she is given the unique opportunity to expand her research. She will travel with a NASA team to a space station where the crew has been stricken with symptoms of a similar inexplicable psychosis—memory loss, trances, and violent, uncontrollable impulses.

Crippled by a secret addiction and suffering from creeping paranoia, Gillian finds her journey becoming a nightmare as unexplainable and violent events plague the mission. With her grip weakening on reality, she starts to doubt her own innocence. And she’s beginning to question so much more—like the true nature of the mission, the motivations of the crew, and every deadly new secret space has to offer.

Merging thrilling science-fiction adventure with mind-bending psychological suspense, Wall Street Journal bestselling author Joe Hart explores both the vast mysteries of outer space and the even darker unknown that lies within ourselves.

Ahoy there me mateys! I received this sci-fi thriller eARC from NetGalley in exchange for an honest review. So here be me honest musings . . . This was categorized as a thriller, which I don't normally read. However the cover and title were fascinating so I went to see what it was about. Well turns out it has a lot of science fiction elements so I happily got a copy. And what a thrilling ride this was! This book follows Dr. Gillian Ryan who studies the brain and a serious new form of dementia. Her fight against the disease is a personal one because it killed her husband. And now her daughter has it too. She needs a cure. The major problem is that her funding has been cut. So when NASA offers her unlimited funding in exchange for a 6 month trip to space to help with astronauts suffering similar problems, can she say no? I found Gillian to be an awesome protagonist that I was continuously rooting for. She has an addiction problem and at times thinks she is going insane. And yet she is smart, driven, and savvy. She will do anything for her daughter. I was riveted by her journey and didn't want to put the book down. The science sections dealing with both the brain and space were fascinating. The novel was character-driven, filled with tension, and truly atmospheric. Poor Gillian is continuously put in harrowing and unexpected situations. Of course nothing goes to plan. The combination of thriller, horror, slight mystery, and sci-fi made this a wonderful read that I highly recommend.

Premises: In the near future, humankind is hit by Losian's, a new dementia-like epidemic, more devastating than Alzheimer. Dr. Gillian Ryan, a radiologist/imagist, lost her husband to the disease and now her 8yo daughter is showing signs of having it too, so she is determined to help find a cure. When she’s on the brink of losing her funding, NASA approaches her with an offer of full permanent funding if only she agrees to go on a space mission to investigate a space station where most of the members have begun to show symptoms similar to Losian's. Under the umbrella of sci-fi setting, this novel is foremost a thriller. The characterization of the main character is very good, you can really feel isolation, claustrophobia, paranoia, addiction, fear. As the for the other characters, nothing memorable and there isn't a lot of character development. Also, I would have liked more of the sciency part: details about the disease and the secret on the space station. If you’re looking for a mystery/thriller with a sci-fi setting and not too many scientific details, this will probably appeal to you.

When I started reading Obscura, I had mixed feelings about the book. For starters, I wasn't crazy about all the time-jumping. I don't mind past and present... one or two aren't bad... but suddenly we're in different years back and forth, and there's a couple chapters in different perspectives. In a thriller, we've got enough to handle with just one or two ways of delivering information. At it's core, though, Obscura is a pretty good book. It has a sort of Michael Crichton sequel flare with elements of the science discussed in The Andromeda Strain and Timeline, but the characters have better depth than some of Crichton's books. For me, the difference was in the believability. When dealing with a murderer and discussing complex scientific subjects, it's usually best to focus one thing and put everything into it. Hart balances between talking about an Alzheimer's-esque disease and teleportation. On their own, they're both interesting and workable in a novel like this. However, when you put them together and add murder, there isn't enough content on any one thing. I would have liked to see a bit more information, research, and experimentation on either of the scientific topics. I ended up enjoying Obscura more than I thought I would. It reminded me of Michael Crichton, and it also reminded me of Dan Brown. I don't read many thrillers, but this one is definitely worth picking up if you stumble across it. It's interesting and gripping.

This was the first book that I’ve read by author Joe Hart. I loved it, and I now own two more that have been added to my TBR pile. Be warned though, Obscura rips your heart out in the very beginning and lodges it firmly in your throat until the very end when it is placed neatly back into your chest. I started it last night before bed, a very bad habit of mine is starting a new book at bedtime, and read way past my bedtime. I read about half last night, and immediately picked it back up this morning and finished before breakfast. Thank goodness I had today off. If I had to go to work leaving this book unfinished I don’t know if I would have been able to concentrate all day. Obscura is a murder mystery set in space, and it’s awesome. The main character is a real person dealing with real issues. I hate it when the main character of a book is perfect and bad things just happen to happen to them. This is not like that. Gillian struggles with addiction, and it’s a large part of the book. The character development in Obscura is extremely well done. The characters are so real that at times I forgot I was reading a book about fictional people. It doesn’t get much better than this.

It is a couple years in our future. A new disease has stricken the world, Losian’s. It is like Alzheimer’s where it erases your memories but it also affects all ages. Dr. Gillian Ryan is one of the lead researchers that is trying to map the path of Losian’s in the brain and has almost discovered it when she suddenly loses her funding. She is desperate to finish her research since Losian’s has taken her husband and is not starting to affect her daughter. Gillian is approached and asked to go to a space station by Mars. It seems the people on the station are starting to show the same signs as those affect with Losian’s. Desperate to find a cure Gillian agrees to go. When Gillian gets out in space she is having withdrawals from a hydrocodone addiction and it is affecting her mind. When she gets to the space station she learns that it’s not just memory loss with crew is suffering with. It seems a murder, suicide, and someone wanting to murder Gillian is on the space station. There is something more happening to the crew and it’s up to Gillian to figure out what if she plans on returning home. This book has everything in it. There is a horrible disease that is starting to affect the human population. Of course there the strange event of Gillian’s finding being pulled at the pivotal moment of discovery but was this done to get her in space? Gillian becomes an unreliable character herself with her addiction. And of course, nothing on the space station is what we expected. This story sucked me in with Losian’s and kept me up late wanting to know what was going to happen next. I love this book, it has a little bit of everything in it. It is one story that you need to check out. I received a complimentary copy of this book. I voluntarily chose to read and post an honest review.

Dr. Gillian Ryan lost her husband to a new and deadly form of dementia, and now her young daughter appears to be succumbing to the same frightening disease. The only chance to save her is a bold research project that can only be accomplished in space, but from the moment of liftoff to the final page, this intriguing psychological thriller crosses genres to blend science fiction into the mix.

I enjoyed the sci-fi/thriller aspect of this story, which is what caught my attention to read this book. The storyline was tense and had some good twists and turns. There were some slow parts and the flashback/flash-forward in the beginning was a bit tedious. But overall, it was a solid read with an interesting premise.

Dr. Gillian Ryan is the leading mind on Losian's, a rare form of dementia that is progressively spreading. Losian's nearly killed her and her unborn child when her husband succumbed to the disease. Years later, her daughter Carrie's condition is worsening and Gillian is desperate to find a cure. When Gillian's funding is suddenly cut, she accepts an offer to collaborate with NASA on a top secret mission in exchange for lifetime funding and a chance to cure her daughter. Gillian agrees to travel to space for six months to observe the crew of a space station who seem to be experiencing symptoms similar to Losian's. As a string of nightmarish events unravel, Gillian is left with nowhere to run and unsure of who to trust. Someone is murdering the crew and Gillian might just be next... Obscura is an action packed sci-fi thriller that will have you on the edge of your seat. I had read some of Joe Hart's work and I really enjoy his writing style, so I was very excited to get a copy of this novel to review. I really love that Gillian has genuine flaws that the author works into the story line perfectly without it distracting from the plot. The novel does transition through several durations of time an events but it was very easy to follow and added to the suspense. I could not wait to figure out how this one would end. This was such a fantastic read that I can't wait to add it to my library as well as other novels he has written.

Obscura is a story about a new form of dementia that does not discriminate age and the lengths people are willing to go to survive. Dr. Gillian Ryan is desperately searching for a cure for the illness that killed her husband and is threatening to take her daughter. She’s invited on a mission in space to work on that cure only to find out she’s been lied to about the mission and her purpose. Obscura is a fantastic mix of science fiction and mystery. Hart is able to mix the two genres in organic ways that keeps the reader hooked. Not only is Obscura a thrilling science fiction mystery, it’s filtered through the lens of an addict desperately trying to fight through her urges. Gillian is an incredibly compelling main character; she’s driven by the loss of her husband, her love of her daughter, and the demands of her addiction. I was able to connect with her immediately as she’s thrown into space layered with politics and secrets. Gillian is a layered main character thoroughly fleshed out, however the secondary and tertiary characters are not. Everyone she interacts with fulfill a purpose rather than being unique individuals. The only issue I have with the novel, and the reason I rated it four stars instead of five, was the climax of the mystery was slightly convoluted and unclear. I’m not asking that Hart hold my hand and explain in excruciating detail what happened, however I am asking for more clarity. Despite the lack of clarity, I thoroughly enjoyed the conclusion of the story and the epilogue. I would absolutely recommend this novel for fans of science fiction and mystery. It’s a quick read that will keep you glued to the pages and will also make you think. I will definitely be reading more of Hart’s work in the future.

Obscura starts with a boom and just gets better. In the future, a disease akin to Alzheimer's is destroying lives both young and old. Our hero, Dr. Ryan, is tasked with going into space and treating some of the astronauts on the shuttle who are suffering from this dreaded and unknown disease. Unfortunately, all goes terribly wrong during the flight. The reader is asked to cope with horrors both real and imagined, not seen except in space and on this cataclysmic flight of mercy. Joe Hart is a very talented writer who will only get better and better. Here, he has proven himself deserving of all the accolades that he has received. Obscura is a book that demands to be read.
