Lucy Barton is a successful writer living in New York, navigating the second half of her life as a recent widow and parent to two adult daughters. A surprise encounter leads her to reconnect with William, her first husband – and longtime, on-again-off-again friend and confidante. Recalling their college years, the birth of their daughters, the painful dissolution of their marriage, and the lives they built with other people, Strout weaves a portrait, stunning in its subtlety, of a tender, complex, decades-long partnership.
