Seventeen years ago. That was the last time Mercy Callahan saw Ephraim Burton, the leader of the twisted Eden cult where she was raised. But even though she escaped the abuse and terror, they continue to haunt her. When her brother Gideon discovers new evidence of the cult's—and their victims'—whereabouts, Mercy goes to Sacramento to reconnect with him. There, she meets Gideon's closest friend—homicide detective Rafe Sokolov. From Rafe, she receives an offer she never knew she needed: to track down Ephraim and make him pay for everything. But Ephraim, who had thought Mercy long dead, discovers she is in fact alive and that she is digging around for the cult's secrets. And now he'll do anything to take her back to Eden—dead or alive.
