After more than twenty years in London, Kate Flynn has abandoned her career as an academic, rented her apartment in the city, and moved back to live with her mother in the grand old house beside a lake where she grew up. Bored and lonely, Kate meets a childhood friend, David Roberts, at the opera. David is married, but Kate finds herself falling for him against her better judgment.

At the same time, David's seventeen-year-old son is visiting Kate's house in secret, attracted by her eccentricity, her wit, and her shelves full of old books and music. Though she knows the risks, Kate cannot quite resist either man. As both father and son set about their parallel courtships, Tessa Hadley's intricate, graceful novel discovers the anxieties of adulthood, and the hazards of refusing to grow up.
