Long Island is a novel by Colm Tóibín, published by Scribner in the United States on May 7, 2024. It is a sequel to Tóibín's beloved novel Brooklyn, revisiting the complex and enigmatic heroine Eilis Lacey more than twenty years later.

Eilis is now in her forties, married to Tony Fiorello, a plumber, and living in a cul-de-sac in Lindenhurst, Long Island in the spring of 1976. Her life is upended when an Irish man arrives at her door with the news that his wife is pregnant with Tony's child. What Eilis does—and refuses to do—in response to this revelation drives the novel's riveting narrative of secrecy, misunderstanding, and love.

A New York Times bestseller, Long Island is a deeply moving story about unfulfilled longings, the thunderous silences of a life lived in isolation within a marriage, and the bonds Eilis rekindles when she returns to Ireland. Tóibín brings his signature precision and emotional depth to this exploration of a woman caught between two worlds, two identities, and two possibilities for her life.
