The #1 New York Times bestselling author of the Otherworld series and Hemlock Island delivers her most suspenseful novel yet, where the discovery of Cainsville's dark past and the true nature of its inhabitants leads to murder, redemption, love, and unspeakable loss.

Olivia Taylor Jones's life has exploded. She's discovered she is not only adopted, but her real parents are convicted serial killers. Fleeing the media frenzy, she took refuge in the oddly secluded town of Cainsville. She has since solved the town's mysteries and finds herself not only the target of its secretive elders but also her stalker ex-fiancé.

Visions continue to haunt her: particularly a little blond girl in a green sundress who insists she has an important message for Olivia, one that may help her balance the light and darkness within herself. Death stalks both Olivia and the two men most important to her, as she desperately searches to understand whether ancient scripts are dictating the triangle that connects them. Will darkness prevail, or does Olivia have the power to prevent a tragic fate?
