Alex Taylor has a large house in the London suburbs, a well-paid job and a beautiful wife. On the surface everything is rosy. But he has a love/hate marriage with no children and is bored by his job. He and his wife, Amanda, communicate by leaving each other notes stuck to the refrigerator door ... Then his world changes. A solicitor tells him that he's been left something in an ex-girlfriend's will - a daughter, Caitlin. A daughter he never knew he had. He also discovers that his wife is having an affair. Now, suddenly alone with a massive new responsibility, how will Alex dodge social services, form a relationship with Caitlin - a thirteen-year-old stranger - and yet put down new roots and rebuild his life from scratch?
