When Alice Hale leaves a career in publicity to become a writer and follows her husband to the New York suburbs, she is unaccustomed to filling her days alone in a big, empty house. But when she finds a vintage cookbook buried in a box in the basement, she becomes captivated by the cookbook’s previous owner—1950s housewife Nellie Murdoch. As Alice cooks her way through the past, she realizes that within the cookbook’s pages, Nellie left clues about her life—including a mysterious series of unsent letters penned to her mother.
Soon Alice learns that while baked Alaska and meatloaf five ways may seem harmless, Nellie’s secrets may have been anything but. When Alice uncovers a more sinister—even dangerous—side to Nellie’s marriage, and has become increasingly dissatisfied with the mounting pressures in her own relationship, she begins to take control of her life and protect herself with a few secrets of her own.
