'Josie's plans for revenge on her rat of a teacher were going perfectly well until Josephine, her future self, turned up to throw a spanner in the works. Josie's two dads called Dave are no help, her wacky grandmother is only interested in her own eco-sabotage plans, and Josie's best friend Ras thinks Josie might be going slightly mad. The only person who wants to help is the bully who made her life hell in year four ... the infamous Quentin Dreadnought may be a whiz in the kitchen but Josie's not convinced he'll be much use against her annoying doppelganger. As Josie's plots for revenge get more inventive, so do Josephine's plans for stopping her.'
