The Liar's Handbook

River’s life is blown apart when his mum invites her new boyfriend into their home and their lives. River is instantly suspicious of Jason – he seems fake, too good to be true. At school, River’s routine fibs are escalating into something more serious, and his teacher gives him a notebook in the hope he can channel his fantasies into creative writing instead. And so, River begins The Liar’s Handbook, and an investigation into Jason.
