Years after the untimely death of her paranormal-investigator mother, fifteen-year-old Violet Addison returns to her Florida hometown to live with her father. Though Violet doesn’t remember much about her late mother, she is certain of one thing: their shared ability to see ghosts and communicate with the dead. But when Violet discovers paranormal activity in the girls’ locker room of her new school, she finds herself ill-equipped for handling the school’s ghostly echoes.

With sharp wit and determination, Violet sets out to uncover the truth behind her school's haunting, to finish the investigation that led to her mother’s sudden death, and to learn why the only ghost she has ever wanted to see is the one that has eluded her forever.
