For thirty-two-year-old Caddie Winger, one summer can make the whole world look different. Jolted out of her comfy, self-made nest and forced to look at the world with new eyes, Caddie begins to take charge of her future -- making a new best friend, taking risks she never dreamed she could, and navigating the depths and shallows of true love and crushing heartbreak. And in the course of one extraordinary season, Caddie will learn how to trust other people ... and, ultimately, how to trust herself.
