The Devil Colony (Sigma Force)
by James Rollins
3.9 Out of 5 Stars (212 Reviews)
Genre: Contemporary Fiction

From New York Times bestselling author James Rollins comes a novel of boundless imagination and meticulous research, a book that dares to answer a frightening question at the heart of America: Could the founding of the United States be based on a fundamental lie? The shocking truth lies hidden within the ruins of an impossibility, a lost colony of the Americas vanished in time and cursed into oblivion. A place known only as The Devil Colony.

Deep in the Rocky Mountains, a gruesome discovery–hundreds of mummified bodies–stirs international attention and fervent controversy. Despite doubts about the bodies’ origins, the local Native American Heritage Commission lays claim to the prehistoric remains, along with the strange artifacts found in the same cavern: gold plates inscribed with an unfathomable script.

During a riot at the dig site, an anthropologist dies horribly, burned to ashes in a fiery explosion in plain view of television cameras. All evidence points to a radical group of Native Americans, including one agitator, a teenage firebrand who escapes with a vital clue to the murder and calls on the one person who might help–her uncle, Painter Crowe, Director of Sigma Force.

To protect his niece and uncover the truth, Painter will ignite a war among the nation’s most powerful intelligence agencies. Yet an even greater threat looms as events in the Rocky Mountains have set in motion a frightening chain reaction, a geological meltdown that threatens the entire western half of the U.S.

From the volcanic peaks of Iceland to the blistering deserts of the American Southwest, from the gold vaults of Fort Knox to the bubbling geysers of Yellowstone, Painter Crowe joins forces with Commander Gray Pierce to penetrate the shadowy heart of a dark cabal, one that has been manipulating American history since the founding of the thirteen colonies.

But can Painter discover the truth–one that could topple governments–before it destroys all he holds dear?

At Princeton University, a famed geneticist dies inside a biohazard lab. In Rome, a Vatican archaeologist is found dead in St. Peter’s Basilica. In Africa, a U.S. senator’s son is slain outside a Red Cross camp. The three murders on three continents bear a horrifying connection: all the victims are marked by a Druidic pagan cross burned into their fl esh.

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 fi rst clue is discovered inside a mummifi ed 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 exlover, 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, Gray will have to sacrifi ce 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.
