Laney and Jake join forces when they learn that the fates of their loved ones are intertwined. And somehow all the danger that dogs their steps, revolves around an eccentric archaeologist's controversial work on Gobekli Tepe, and the search for an ancient source of power.

Their personal quest soon becomes a race to protect humanity's very existence. How, though, can they defeat a foe who has been planning his moves for millennia? To save mankind, Laney and Jake know they must succeed.

But to succeed, they must live long enough to fight.
