Emily Delahunty is an eccentric British romance novelist who lives in Umbria in central Italy. One day while travelling, the train she is on is bombed by terrorists. After she wakes up in a hospital, she invites three of the other survivors of the disaster to stay at her Italian villa for recuperation. Of these are The General, a retired British Army veteran, Werner, a young German man, and Aimee, a young American girl who has now become mute after her parents were both killed in the explosion.

When her social-climbing father is relocated from a one-horse town to his native Rome, 12-year-old Caterina enrolls in his old school, finding herself adrift in an environment where eighth-graders form friendships based on social class and their parents' political affiliations.
