Marin Williams’s life is seemingly perfect. She lives in a gorgeous farmhouse in Sugar Hill, New Hampshire with her handsome husband, Scott, her young son, Jesse, and the collies she boards and trains as an elite dog trainer. But there’s only one thing missing: a second child. Determined to have the nuclear family she’s always wanted, Marin suffers miscarriage, after miscarriage, after miscarriage… until, one day, she gives up. Her dreams of the model family are dashed… that is until, Lisa, a friend of a friend, volunteers to carry her baby for her. Arrangements are made and Lisa moves into the flawless white farm house into a room all her own. Soon all of Marin’s dreams are coming true until Lisa starts stepping over boundaries Marin didn’t even know she had, didn’t even know she needed to have. As Lisa gets accustomed to living in the exquisite white farm house with the wraparound porch, she also gets accustomed to becoming the focus of Scott’s attention, and she also comes to find that she wouldn’t mind becoming Marin as well.
