Whether she becomes a friend or a rival afterwards is written in the stars, but also somewhat within our control. For both women and men, a sister is often one of the most important people in life. The most beautiful stories about lifelong sisterly bonds by T. C. Boyle, Jane Austen, Benedict Wells, Jodi Picoult, Ian McEwan, Anna Gavalda, John Irving, Ali Smith, Vladimir Nabokov, Margaret Atwood, Madeleine Bourdouxhe, and many others.
