The author of more than a million books sold brings a gripping saga of the little girl who goes missing in 1943 and the sister who remains, forced to live with the consequences of the event for the next seventy years of her life. When cold case agent Meghan DeFord is forced to take a six-week leave-of-absence after a traffic accident, she chooses to spend the time with her grandmother, whose eightieth birthday is approaching. Meghan has wonderful memories of childhood summers with her Grandma Hazel and anticipates a time of relaxation and filling a scrapbook with pictures of their time together. Meghan's mother, Diane, arrives unexpectedly and brings her long resentment towards Hazel for her overprotectiveness and near paranoia. During their time together Hazel confesses her long-held secret: when she was a child, her little sister disappeared and no one ever found out what happened to her. That loss skewed Hazel's view of the world and affected every relationship. Meghan determines to discover not only what happened to Maggie, but to heal the rift between the two women she loves most in the world.
