Set in postwar Italy, the novel follows a poor child sent by train from the devastated south to live temporarily with a northern family as part of a government relocation program; through encounters with strangers, unexpected kindness and harsh realities, the child confronts cultural divides, hunger, and loss while discovering resilience, love and the painful compromises of adulthood. Themes of social injustice, maternal sacrifice and the long echoes of a single formative summer shape a tender, bittersweet coming-of-age portrait against the backdrop of a country rebuilding itself.
