“James Rollins knows adventure.”
—Chicago Sun Times
With The Doomsday Key—the latest Sigma Force blockbuster from New York Times bestselling author James Rollins—the critically acclaimed thrill-master continues to dazzle with an electrifying combination of history, religion, science, and adventure. The hero of Map of Bones, The Black Order, and other exceptional Rollins roller-coaster rides, Commander Pierce returns to solve a centuries-old secret, one coded in prophecies of doom—in a story that fans of Michael Crichton, Douglas Preston, and Indiana Jones will not be able to put down!
James Rollins is the author of international thrillers that have been translated into more than forty languages. His Sigma series has been lauded as one of the “top crowd pleasers” (New York Times) and one of the “hottest summer reads” (People magazine). In each novel, acclaimed for its originality, Rollins unveils unseen worlds, scientific breakthroughs, and historical secrets—and he does it all at breakneck speed and with stunning insight. He lives in the Sierra Nevada.
“This guy doesn’t write novels—he builds roller coasters....Rollins excels at combining action and history with larger-than-life characters....A must for pure action fans.” — Booklist
“Rollins’s prose explodes off the page in a twisty and compelling thriller....Swashbuckling adventure, elite team effort, and religious symbology all add up to another gripping and terrifying read....An amazing and brilliant technothriller that might be his best to date. — Library Journal (starred review)
