Rayne Goodman is excited to celebrate her 17th birthday with her mom and some friends in their small town of Walworth, NY. The day before, however, Rayne receives a frantic call from her mother, instructing her to go stay with her best friend and call a mysterious number written on a small, gray business card. That is the last time Rayne hears from her. Convinced that something bad has befallen her mother, she calls the mysterious number and, together with best friend, Quinn, she enters into a world that looks a lot like her own, but with some glaring differences: Rayne's life with her mother is not what she thought it was.

About 18 years ago a plague of demons was accidentally set loose upon a small town in Oneida County, New York. Now, some of those demons, both literal and figurative, have found their way into Rayne's calm, safe world and have shattered it before her eyes. Connecting with an old childhood friend of her mother's, Dr. Theodore Williams, Rayne is forced to flee from her home to a safe house, where she learns about who her mother really is, where she came from, and why her own birth is now so important. Now, with Quinn, Dr. Wiliiams, and his charismatic nephew Lucas, Rayne is tasked with facing off against the new leader of a dangerous religious cult. In a tale filled with good and evil, a little magic, teenage insecurities, and maybe even a few romantic sparks, Rayne will need to come to terms with her true identity and face down a formidable villain in order to save her mom.
