Kate touches the Witch's Tree on a dare and finds herself bound to the Witchwood Boys: three supernatural witches in leather and iron masks — Brooks, Tanner, and Marlow — who insist she is now part of their coven. What looks like an urban legend turns horrifyingly real as the Hag Wytch, a forest god who eats living people, enters the picture and the magic of the witchwood demands increasingly extreme rituals.

Kate is a practical, witty woman thrust into an impossible situation with three men who are alternately infuriating and compelling. She has a sharp voice and refuses to be passive, even when surrounded by literal supernatural horror. The series is written in first person and her narration is a core part of its appeal.

Across four books, Kate and the Witchwood Boys move from hostility to a chaotic, volatile bond as they fight to close the gate to the Hag Wytch's supernatural prison. The series blends cozy urban fantasy atmosphere with explicit content and campy horror, featuring blood sacrifice, ritual magic, and a reverse harem that grows darker and more emotionally complex with each book.
