Second Nature / Alice Hoffman

Robin Moore, coping with a divorce and a troubled teen-aged son, impulsively rescues a strange man from a psychiatric ward—a beautiful, uncivilized innocent who has been raised in the wilderness and possesses no more sophistication than a child. But when she brings him home to her perfectly ordered neighborhood, the events that follow cause Robin to question her wisdom and doubt her own heart—and, ultimately, to change all of her ideas about love and humanity.
