Superhuman-enhanced Heka assassins? Near-immortal Facetakers who can swap bodies at will? Sarah should have run when she had the chance. Instead, she is swept into a secret war that has been raging in the shadows through the ages. And now the conflict takes an unprecedented turn as the deadly groups plunge back in time to fight for control over pivotal moments in history. If that unrivaled source of new power is unleashed, it could usher in a new form of world slavery. Sarah has no superhuman enhancements or freakish soul powers, but she does have the help of a pair of rogue facetakers already hunted by both sides, her new boyfriend Tomas, who is not who he claims to be, and a hotheaded young rune expert whose mission is to kill them all. To survive, Sarah must confront an enemy she cannot hope to defeat, and become the Memory Hunter.
