When four women leave their drab lives behind to go on holiday in Italy, their lives are changed forever by the Mediterranean. Mrs. Arbuthnot and Mrs. Wilkins, while part of the same ladies' club, have never spoken. Lady Caroline Dester and the elderly Mrs. Fisher join their holiday so as to mitigate expenses. As these women come together and learn more about themselves than they ever thought possible, they reveal their true personalities and the backdrops of their lives that tend to hinder them. Inspired by the author's own month-long trip to the Italian Riviera, this novel is noted as her most widely-read work.
