Murphy Blackwell hides inside her heavily warded Victorian home in quiet Gryphon, Alabama, to protect the world from her dangerous power. Murphy is a gray witch—a chaos witch—the most unusual and hazardous type, and she knows what happens when she ventures past the boundary of her protective spells. She has only two friends, both members of her coven. The three have shared an inseparable bond after all three of them lost their mothers during an attack on their coven. The killers were never found.

Murphy's life is turned upside down when a gunman enters her home, shattering her sense of safety. Then, her high priestess delivers a new blow that changes everything Murphy thought she knew about herself and her magical ability. The chaos Murphy knew was only the start of the disaster to come.
