In A.D. 327, a Roman galley with an extraordinary cargo barely escapes a pirate attack. In 1916, a British warship mysteriously explodes in the middle of the North Sea. In the present day, a cluster of important mosques in Turkey and Egypt are wracked by explosions.

What ties them all together? NUMA director Dirk Pitt and his team are about to find out, as Roman artifacts discovered in Turkey and Israel unnervingly connect to the rise of a fundamentalist movement determined to restore the glory of the Ottoman Empire. From Washington to London to the treacherous shores of the Near East, dangerous men and desperate acts fill their path, and at the end of it, the most dangerous thing of all: the rumored existence of a mysterious “Manifest,” lost long ago, which if discovered again . . . just might change the history of the world as we know it.
