The horrific theft of a priceless relic...a secret society reaching back to the Middle Ages...and the top-flight US team who must stop them. A heart-stopping SIGMA Force thriller from NEW YORK TIMES bestselling author James Rollins.

When a group of parishioners is burned to death in a German cathedral, the US sends in SIGMA Force. For this 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 Three Kings.

Pierce and his team follow a trail that leads from Europe's Gothic cathedrals through the remnants of the seven wonders of the ancient world to a mystical place where science and religion unite to unleash a threat not seen since the beginning of time itself...
