The book opens with Becky living with her boyfriend Luke in Manhattan (both are from England). She has finally found her career calling as a personal shopper at Barney’s and is happily helping her best friend Suze plan her wedding. Becky is shocked when she catches Suze’s bouquet and finds a marriage proposal from Luke in it. Suddenly, she finds herself caught in the middle between her mother and Luke’s mother, both of whom want to throw her a lavish wedding, one in England and one at the Plaza in New York. The problem? Becky can’t seem to tell either of them no, even as both weddings are being planned for the same day.
