In Sister, Mother, Husband, Dog, Delia Ephron brings her trademark wit and effervescent prose to a series of unforgettable, moving, and provocative essays. The emotional linchpin in this collection is the author’s stirring, eloquent response to the death of Nora Ephron—Delia’s older sister and frequent writing companion. In “Sister,” Ephron deftly captures the love, rivalry, respect, and intimacy that made up her relationship with her sister in a way that is at once deeply personal and comfortingly universal.
