In 1962, Kitty Miller is a single, thirty-eight-year-old woman who enjoys running a bookstore with her best friend. But in her dreams, she becomes Katharyn Andersson, a married mother of three young children. At first, she thinks her nighttime forays into the life she thought she always wanted are just a product of a vivid imagination. But the lines between dreams and reality begin to blur, and Kitty isn't sure which world is real and in which one she belongs.
