Brad Thor, master of suspense and New York Times bestselling author of The First Commandment, returns with his highest-voltage thriller to date. In a pulse-pounding, adrenaline-charged tour de force, Navy SEAL turned covert Homeland Security operative Scot Harvath must race to locate an ancient secret that has the power to stop militant Islam dead in its tracks.

June 632 A.D.: Deep within the Uranah Valley of Mount Arafat in Mecca, the Prophet Mohammed shares with his closest companions a final and startling revelation. Within days, he is assassinated.

September 1789: U.S. Minister to France Thomas Jefferson, who is charged with forging a truce with the violent Muslim pirates of the Barbary Coast, makes a shocking discovery - one that could forever impact the world's relationship with Islam.

Present day: When a car bomb explodes outside a Parisian café, Scot Harvath is thrust back into the life he has tried so desperately to leave behind. Saving the intended victim of the attack, Harvath becomes party to an amazing and perilous race to uncover a secret so powerful that militant Islam could be defeated once and for all without firing another shot, dropping another bomb, or launching another covert action.

But as desperate as the American government is to have the information brought to light, there are powerful forces aligned against it - men who are just as determined that Mohammed's mysterious final revelation continue to remain hidden forever.

What Jason Bourne was to the Cold War, Scot Harvath is to the War on Terror. Brad Thor has created "the perfect all-American hero for the post September 11 world" (Nelson DeMille) and will keep readers glued to the pages as he once again takes them across the globe on a heart-pounding chase where the stakes are higher than they have ever been before.
