The author of five blockbuster novels, Emily Giffin, delivers an unforgettable story of two women, the families that make them who they are, and the longing, loyalty and love that binds them together Marian Caldwell is a thirty-six year old television producer, living her dream in New York City. With a fulfilling career and satisfying relationship, she has convinced everyone, including herself, that her life is just as she wants it to be. But one night, Marian answers a knock on the door . . . only to find Kirby Rose, an eighteen-year-old girl with a key to a past that Marian thought she had sealed off forever. From the moment Kirby appears on her doorstep, Marians perfectly constructed world—and her very identity—will be shaken to its core, resurrecting ghosts and memories of a passionate young love affair that threaten everything that has come to define her. For the precocious and determined Kirby, the encounter will spur a process of discovery that ushers her across the threshold of adulthood, forcing her to re-evaluate her family and future in a wise and bittersweet light. As the two women embark on a journey to find the one thing missing in their lives, each will come to recognize that where we belong is often where we least expect to find ourselves—a place that we may have willed ourselves to forget, but that the heart remembers forever.
