When Kathleen Deane’s husband, Tom, tells her he's no longer happy with his life and their marriage, Kathleen is confused. They live in Kansas. They’ve been married thirty years. Who said anything about being happy? But with Tom off finding himself, Kathleen starts to think about what she wants. And her thoughts lead her to a small beach community on the east coast, a town called Whitbey that has always looked lovely in the Christmas letters her childhood friend Josie sends every year.
