The "soul stirring" masterpiece by the New York Times bestselling author of Room.

A retired professor's life is thrown into chaos when he takes his great-nephew to the French Riviera.

Noah Selvaggio is a retired chemistry professor and widower living on the Upper West Side, but born in the South of France. He is days away from his first visit back to Nice since he was a child, bringing with him a handful of puzzling photos he's discovered from his mother's wartime years. But he receives a call from social services: Noah is the closest available relative of an eleven-year-old great-nephew he's never met, who urgently needs someone to look after him. Out of a feeling of obligation, Noah agrees to take Michael along on his trip.
