As a gray witch, twenty-six-year-old Murphy Blackwell lived an isolated life, sheltering the world from her damage. Gray witches are chaos witches—the most hazardous type known to humankind. She was to blame for the mayhem that occurred whenever she ventured outside of Witch's Brew, her heavily warded home and business, and there was little she could do about it. Her only friends were two coven members with whom she shared an inseparable bond after the night all three of them lost their mothers. The killers were never found.

Betony is a strong-willed high-schooler determined to learn all there is about the craft. As her primary instructor, she has adopted Murphy, a solitary practitioner, but Murphy isn't sure about her aspiring student's designs. Betony says all the right things. So why is Murphy second-guessing her motivation?

Then, her high priestess delivers a new blow, one that endangers everything—including her survival, and the survival of the entire town of Gryphon.
