“Bone-chilling.” –Publishers Weekly (Starred Review)

“One of the best in the series.” –Booklist (Starred Review)

To save mankind’s future, the members of Sigma Force must make a devil’s bargain as they join forces with their most hated enemy to stop an ancient threat in this gripping adventure from #1 New York Times bestselling author James Rollins.

Off the coast of Brazil, a team of scientists discovers a horror like no other, an island where all life has been eradicated, consumed, and possessed by a species beyond imagination. Before they can report their discovery, a mysterious agency attacks the group, killing them all, save one: an entomologist, an expert on venomous creatures, Professor Ken Matsui from Cornell University.

Strangest of all, this inexplicable threat traces back to a terrifying secret buried a century ago beneath the National Mall: a cache of bones preserved in amber. The artifact was hidden away by a cabal of scientists—led by Alexander Graham Bell—to protect humankind. But they dared not destroy it, for the object also holds an astonishing promise for the future: the very secret of life after death.

Yet nothing stays buried forever. An ancient horror— dormant in the marrow of those preserved bones—is free once more, nursed and developed into a weapon of incalculable strength and malignancy, ready to wreak havoc on an unsuspecting world.

To stop its spread, Commander Grayson Pierce of Sigma Force must survive a direct attack on the island of Maui. To be there first has always been the core mission of Sigma Force, a covert team forged to be America’s front line against emerging threats. But this time, even Sigma may not be able to decipher the deadly mystery, one that traces back to the founding of the Smithsonian Institution.

With each new discovery, the menace they hunt is changing, growing, spreading—adapting and surviving every attempt to stop it from reconquering a world it once ruled. And each transformation makes it stronger . . . and smarter.

Running out of time and options, Commander Grayson Pierce will be forced to make an impossible choice. To eradicate this extinction-level threat and expose those involved, he will have to join forces with Sigma’s greatest enemy—the newly resurrected Guild—even if it means sacrificing one of his own.

Enjoy reading this series. He does not fail to pull you into the storyline and keep you hooked until the last word. Thought provoking science, locations, and other literature mentioned entice you to look into the information yourself. Chilling how current discoveries have the possibility of finding such Lazarus creatures larger than a single cell critter. Back to the book, I admire the way he has had the different characters evolve throughout the series. Makes them people you could actually know out of the pages of the book. One of my favourite Authors, hope Mr Rollins continues to be so creative for a very long time.

First off, thank you to William Morrow imprint and the Harper Collins publishing company for sending me a physical ARC of the newest in one of my absolute favorite series of all time. They paid me nothing, and all I had to do was read it and review it honestly. Sigma Force novels are always action-packed roller coaster rides of thrills and emotions. Rollins always seem to find a way to up the game to huge stakes, but not seem so utterly ridiculous that the situation becomes unbelievable. Not to say there aren't some unbelievable moments in some of these books, but that's a genre-thing. Rollins, who also is a trained veterinarian, has a love and respect for science and technology, which is evident in his books. Sure, the theories he posits might be out there or a stretch on the imagination, but he's always sparked by something real he's read about, and researched thoroughly. His blend of history, technology, science, and action really works for me. The Demon Crown was definitely one of the stronger entries in the series. The villain was a little bit of a Bond villain, but it worked for the story, since The Guild and its agents have played a pivotal role in the course of the series, driving much of the action for the beginning of the series and helping facilitate some key character growth in many of the major players on both sides of the good-evil spectrum. Many fan favorites are in danger in this one, thanks to the threat -- which is absolutely terrifying. The Ezekiel Boone-esque menace of global-balance-upsetting proportions is both riveting to read (you won't want to look away!) and downright scary. I can't say much more without spoiling stuff, but if you haven't picked up Sigma Force, you should. It's a fun ride, with lots of ups and downs and action along the way. I wouldn't recommend reading this without reading the rest of the series, unless you don't mind stuff being spoiled, because quite a few things in this one are based off the events of the other books -- and you won't appreciate the characters and their plotlines and growth stories here without that history. But I can 100% recommend the series overall. Pick up book one (and push through if you have to, it's the slowest in the series, in my opinion) and binge them. DO IT.

Another excellent Rollins novel! Like all Sigma Force stories this one does not dissapoint. No one compares to James Rollins when it comes to action packed, nail biting, heart pounding adventure. Absolutely love this authors writing style, whether its the Sigma series or stand alone books. Can't get enough of him. Thank you once again for an outrageous ride!

This is part of the Sigma series and is better if read in order. Sandstorm is the first book. I actually discovered this series the third book in, I wasn't aware it was part of a series. But I liked it so I started from the beginning. I have also read several of his stand alone novels which are also really good. This is one of those installments where things come full circle, in a very unique way. Before Sigma was Sigma, something deadly dangerous was discovered, and hidden away in hopes of protecting the human race. But an enemy set on revenge has found this deadly dangerous thing and decides to use it to not only get his revenge, but to bring his home country back to its imperial glory back once again. As usual, Sigma once again gets pulled into a mystery that holds the fate of the world in its grasp, but they have just a few days to unravel it, or the world as they know it will be forever changed, and this time someone close to Pierce could die, if the answer remains shrouded from them. This installment wasn't quite as action packed like other books in this series, but I still enjoyed the story, and Rollins still does an excellent way of melding and molding a tale around actual history and science elements. I look forward to following the next mission.
