Long Island unfolds as an intensely moving narrative of secrecy, misunderstanding, and love. We re-encounter Eilis Lacey, the complex and enigmatic protagonist of Brooklyn, now navigating life twenty years later. Eilis, an Irish native, is intertwined with the life of Tony Fiorello, an Italian American plumber. Together, they have forged a life amidst the sprawling family dynamics of Tony's relatives on Long Island.

The year is 1976, and Eilis, in her forties with two teenage children, finds herself without a support system in this still-foreign land. Her connections to Ireland are palpable and potent, yet she has not revisited her homeland in decades. A startling encounter occurs when an Irishman arrives at her door, claiming his wife is pregnant with Tony's child, and intends to leave the baby with Eilis upon its birth.

The narrative masterfully explores Eilis's response to this shocking revelation. Long Island is a tale of unspoken longings and the perilous silences that pervade Eilis's existence. Tóibín's skillful storytelling gives voice to these silences, weaving a poignant story of a woman's solitary struggle within her marriage and the profound connections she reestablishes upon her inevitable return to her origins, rediscovering past ways of life and love once thought lost.
