In this heart-stopping novel by #1 New York Times bestselling author James Rollins, an elite team of ex-Special Forces soldiers turned scientific specialists must uncover a secret society and the treasure that could destroy the world.

When a group of parishioners are burned to death in a German cathedral, the U.S. sends in the Sigma force. The tragedy is more than a case of arson; someone has stolen the priceless treasure stored in the cathedral's golden reliquary: the bones of the Biblical Magi, the legendary Three Kings.

Commander Logan Pierce, new to Sigma, will lead a team on the hunt for the Royal Dragon Court, a clandestine aristocratic fraternity of alchemists dating back to the Middle Ages, who seek to establish a New World Order using the mystical bones. The Sigma team will follow a labyrinth of clues leading from Europe's gothic cathedrals, through the remnants of the Seven Wonders of the ancient world, to a mystical place where science and religion will unite to unleash a threat not seen since the beginning of time itself.
