In this electrifying adventure from James Rollins, the #1 New York Times bestselling author of the Sigma Force series, Commander Gray Pierce returns to solve a centuries-old secret, one coded in prophecies of doom. At Princeton University, a famed geneticist dies inside a biohazard lab. In Rome, a Vatican archaeologist is found dead in St. Peters Basilica. In Africa, a US Senator’s son is slain outside a Red Cross camp. Three murders on three continents bear a horrifying connection: all the victims are marked by a Druidic pagan cross burned into their flesh. The bizarre murders thrust Commander Gray Pierce and Sigma Force into a race against time to solve a riddle going back centuries, to a ghastly crime against humanity hidden within a cryptic medieval codex. The first piece of the puzzle is discovered inside a mummified corpse buried in an English peat bog-a gruesome secret that threatens America and the world. Aided by two women from his past–one his ex-lover, the other his new partner–Gray must piece together the horrifying truth. But the revelations come at a high cost, and to save the future, Pierce will have to sacrifice one of the women at his side. That alone might not be enough, as the true path to salvation is revealed in a dark prophecy of doom. Sigma Force confronts humankind’s greatest threat in an adventure that races from the Roman Coliseum to the icy peaks of Norway, from the ruins of medieval abbeys to the lost tombs of Celtic kings. The ultimate nightmare is locked within a talisman buried by a dead saint–an ancient artifact known as the Doomsday Key.

For her instructors in the twenty-first century, it meant painstaking calculations and careful monitoring of the rendezvous location where Kivrin would be received. But a crisis strangely linking past and future strands Kivrin in a bygone age as her fellows try desperately to rescue her. In a time of superstition and fear, Kivrin—barely of age herself—finds she has become an unlikely angel of hope during one of history’s darkest hours.

In this superb thriller from #1 New York Times bestselling author James Rollins, Sigma Force must battle a group of rogue scientists who have unleashed a diabolical project that could bring about the extinction of mankind. Salvation . . . or annihilation? What if scientists could bio-engineer the next great world prophet—the next Buddha, Mohammed, or even Jesus? Would it mark the Second Coming or initiate a chain reaction leading to the end of mankind? Formed during the Cold War, a think tank of world scientists known as the JASONS have discovered a way to manipulate and enhance autistic children who show savant talents—mathematical geniuses, statistical masterminds, brilliant conceptual artists. Yet among their young patients a strange side-effect begins to arise. Before it can be analyzed fully, a rogue group of the JASONS begins their own secret experimentation with a cadre of the best children. Their goal, to create a world prophet for the new millennium, one who can be manipulated to create a new era of global peace . . . a peace on their own terms, that is. But such manipulation has grim consequences as a biological meltdown among the children begins to occur—turning the innocent into something far more frightening. To stop the JASONS before they engineer the extinction of mankind, Commander Gray Pierce of SIGMA Force races against time to solve a mystery that dates back to the first famous oracle of history—the Greek Oracle of Delphi. But can the past save the future?
