A U.S. military satellite crashes, and a search is conducted to recover its valuable cargo. But, the satellite turns up something chilling: an image of the eastern U.S. seaboard in ruin. Meanwhile, the Vatican receives a package from a vanished colleague. It contains a skull scrawled with Aramaic and a tome bound in human skin. The source of these items: Ghengis Khan, whose tomb allegedly hides vast treasure. Now, Sigma Force must solve a mystery that leads back to Christianity's roots.

In the wilds of Mongolia, a research satellite has crashed, triggering an explosive search for its valuable cargo: a code-black physics project connected to the study of dark energy -- and a shocking image of the eastern seaboard of the United States in utter ruin. At the Vatican, a package arrives containing two strange artifacts: a skull scrawled with ancient Aramaic and a tome bound in human skin. DNA evidence reveals that both came from the same body: the long dead Mongol king Genghis Khan. Commander Gray Pierce and Sigma Force -- joined by a pair of Vatican historians -- race to uncover a truth tied to the fall of the Roman Empire, to a mystery going back to the birth of Christianity, and to a weapon hidden for centuries that holds the fate of humanity.
