A mysterious, power-mad enemy is bent on snatching ancient artifacts, and murdering anyone who gets in their way. Despite their relentless efforts, they have failed to track down the one relic they most desperately need. Brilliant but unemployed librarian Erin Turner becomes the pawn in their vicious conspiracy, forced to hunt for a relic no one can even describe—but if she can't find it, everyone she loves will die. To find the relic, Erin must team up with disgraced archaeologist Alex MacKay on a pulse-pounding quest to rip open a secret buried so deep that unearthing it just might destroy the world.
