When seventeen-year-old necromancer Sapphire Sweetman befriends the spirit of Mona Delaney, she thinks all of her problems have been solved. Mona proves to be very useful when it comes to propelling her up the social ladder at school and dishing out haunting - and sometimes frighteningly cruel - punishments to those that Saffy deems deserving, but soon she begins to realize that Mona isn't quite who she says she is. People across the county are vanishing without a trace, and when Mona demands a sinister favour in return for her loyalty, Saffy's world is upended completely. The options are clear: comply, or become subject to the rage of a spirit who is far more powerful than she first seemed. Highest chart positions: #12 in Paranormal
