"Tuck's prose is elegant." -- New York Times Book ReviewLily Tuck's critically-lauded, bestselling I Married You for Happiness was hailed by the Boston Globe as "an artfully crafted still life of one couple's marriage." In her singular new novel Sisters, Tuck gives a very different portrait of marital life, exposing the intricacies and scandals of a new marriage sprung from betrayal. Tuck's unnamed narrator lives with her new husband, his two teenagers, and the unbanishable presence of his first wife--known only as she. Obsessed with her, our narrator moves through her days presided over by the all-too-real ghost of the first marriage, fantasizing about how the first wife lives her life. Will the narrator ever equal she intellectually, or ever forget the betrayal that lies between them? And what of the secrets between her husband and she, from which the narrator is excluded? The daring and precise build up to an eerily wonderful denouement is a triumph of subtlety and surprise. With Sisters, Lily Tuck delivers riveting psychological portrait of marriage, infidelity, and obsession; charting with elegance and insight love in all its phases.
