Delia and Nora Ephron were writing partners; they co-wrote the movies You've Got Mail and The Sisterhood of the Traveling Pants as well as the off-Broadway hit Love, Loss and What I Wore. Delia was an assistant producer on Nora's film Sleepless in Seattle.
In her latest book, Sister Mother Husband Dog, novelist Delia Ephron writes that losing her older sister, Nora Ephron, was like "losing an arm, it's that deranging." Nora, who wrote When Harry Met Sally, died of acute myeloid leukemia in June 2012.
But for all their collaboration and closeness, Delia acknowledges that sister relationships are complicated. Sister Mother Husband Dog is a collection of autobiographical essays.
