Eilis Lacey is Irish, married to Tony Fiorello, a plumber and one of four Italian American brothers, all of whom live in neighboring houses on a cul-de-sac in Lindenhurst, Long Island, with their wives and children and Tony's parents, a huge extended family that lives and works, eats and plays together. It is the spring of 1976 and Eilis, now in her forties with two teenage children, has no one to rely on in this still-new country. Though her ties to Ireland remain stronger than those that hold her to her new land and home, she has not returned in decades. One day, when Tony is at his job and Eilis is in her home office doing her accounting, an Irishman comes to the door asking for her by name. He tells her that his wife is pregnant with Tony's child and that when the baby is born, he will not raise it but instead deposit it on Eilis's doorstep. It is what Eilis does, and what she refuses to do, in response to this stunning news that makes TÔoibÔin's novel so riveting.
