When her mother is sent to prison for three months for assaulting a policeman with a stiletto shoe, fifteen-year-old Caris goes gently off the rails. Whilst her taxi-driver father Mac attempts to keep the family together, Caris meets George, a boy from the other side of the vale and from a very different sort of family. Their relationship leads her away from school and what she has known, into a new and unnerving world - and looks set to throw the family into terrifying chaos.
