Sixteen-year-old Caitlyn Foster never believed in the legend of the Redeemers. That was before the trees started to whisper her name, before a murder of crows attacked the town, and before she and her family came home to find a bloody handprint on their front door, marking one of them as a sacrifice. As Caitlyn's friends are ripped from their homes, she knows it's only a matter of time before the Redeemers come for her. Caitlyn has the power to stop the terror, but she'll have to decide if she's willing to sacrifice herself to save those she loves.
