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.


  • Great thriller!

    By gastuder
    Thanks again, Mr. Rollins! As always, a suspenseful, thrilling, and breath taking, read! You make it so easy for the reader to visualize the scenery and experience what the characters are experiencing.
  • Fast moving

    Exciting. Propel the reader to continue along twists and turns. Could have done with less in the mind of a predator passages. The rest was great.
  • Interesting hypothesis

    By danmatras
    I enjoyed this book maybe not as much as some of Mr. Rollins previous books. The plot was interesting but I think it dragged a little in the final third of the book. It’s seem to take too long for things to be resolved It seemed impossible for everything to be done in the time frame in the book.

    As always with Rollins, this book is an excellent read. With its tightly woven action, characters that are finely drawn, whether good folk or bad folk, and a unique but plausible story line all built around Sigma Force, Demon Crown is hard to put down.

    Takes awhile to get into the book, but if you stick with it you are rewarded with an exciting and interesting read.
  • Another great book!

    By Kidney disease
    Rollins, with his amazing imagination, brings together a group of old friends to save the world again. Can’t go wrong here.
  • Another hit

    By Dkldragon
    I have read all of Rollins books and there has never been a mediocre read. This book was as engrossing as every other one written by Rollins. Once I got started- I couldn’t put it down. Thanks again for giving me a book to look forward to every year. Ready for the next one!!!

    Rollins delivers again! Weaving many of the stalwart characters we love (and an enemy we loathe) with a group of new friends with serious scientific prowess and a fast paced plot we have another great page turner. Even after a dozen and a half Sigma Force novels I actually can’t wait for the next one!
  • Hmm

    By ScubaDyer
    Imagine a book about insects written by Tom Clancy. Pedantic.

    Rollins lost his stunning story lines and epic thriller events in this book. I found the science boring and the characters dull. It was an incomplete read for me- could not even finish it! I have read all the other Rollins’ books so it is weird for me to make these comments. Try again soon?
