Moving to the country away from all her friends has done nothing to improve Chloe's six-month-long bad mood. And neither has her parents' latest news. Why do they want to adopt a two-year-old boy? Are they trying to replace her? Where's her probably-very-glamorous real mother when she needs her? Determined to have nothing to do with this new addition to the family, Chloe makes herself as unpleasant as possible. But then she meets her new brother Ollie and realizes that he really needs her help. When his violent father arrives at their house one day in a drunken rage, and Chloe has to save him from harm, her growing feelings for Ollie are cemented, and she realizes that they can live together as one family.
