This book presents a week in the lives of seven people--all on the same route to school. Harriet is waiting for her husband to tell her if their marriage is on or off, while Pippa is about to receive some potentially devastating hospital results. Evie has one week to save her career, and Nick's wife died two years ago, leaving him with a troublesome teenage daughter. Martine, a French au pair, is about to run off with a married man while Kitty accepts a bet to find a man in a week. And Betty watches by the roadside, looking for the driver who killed her son. Little do any of them know that by the end of the week, the school run will have become a collision course, connecting their lives in more ways than one.
