The doctor's office is cool, white, sterile. But the doctor's words are searing: blood tests prove beyond a shadow of a doubt that Margaret and Arthur Crawfield's beloved, dying son is not their child. Now they must face Peter's death and the shock of having a son they have never met. Grieving, yet compelled, they begin a search that will tear two families apart.

Laura and "Bud" Rice share an elegant home and two children, brilliant, handsome Tom, and cherished, chronically ill eleven-year-old Timmy. But after nineteen years of marriage, Laura's respectable husband is a stranger—and the reason for Tom's escalating involvement with a group of campus bigots. Suddenly the Crawfields enter their lives and shatter their fragile world. As the Rices' quiet Southern town explodes with hate and violence, the two familes must embrace—or be destroyed by—the shattering truth.
