Caroline Prater: A lost twin. A widow. A pregnant woman. When she discovers she has a twin living in an Arizona town called Shelter Valley, Caroline Prater decides to go there. Pregnant and a widow, she leaves her Kentucky hometown and drives west. She'll try to connect with her twin sister, Phyllis Sheffield. And she'll seek out John Strickland, the father of her baby–if only to let him know. John is a well-known architect, a still-grieving widower who's settled in Shelter Valley. He and Caroline met six weeks earlier when he traveled to Kentucky.... Caroline's waiting for the right moment to approach Phyllis, unsure whether her unsuspecting twin will welcome her presence. And she develops a deeper relationship with John–but that's just for the baby's sake. Or is it?
