Deep in the mountains of Perry County, Kentucky, a troubled young woman enters a new life of magic and danger. Wren is fresh out of high school, and her life is a mess. Her mother is dying, her aunt couldn't be more overbearing, and her moods are wildly unpredictable. On a mission to self-destruct, she's driving her aunt crazy with drinking and broken curfews. But Wren isn't just acting out-something inside her is changing. After being attacked by a red-eyed man and being rescued by a beast that transforms into a gorgeous boy before her eyes, Wren discovers that she's a shifter, able to take the form of any animal she makes contact with. Complicating matters, Wren finds out she is a special kind of shifter-a tracker-and a powerful vampire needs her help to find the rogues of his clan who are planning to destroy the town, and everyone in it. In return for her help, she's promised the one thing she wants the most-her mother to be cured. Wren will have to choose between the safety of a familiar embrace and the fiery touch of the boy who makes her question everything she thought she knew. In order to survive the trials ahead, she'll have to open her heart, and find the strength of the woman she's destined to become.
