Summer, 1987. On the sweltering streets of the dying New England mill town of Swift River, sixteen-year-old Diamond Newbury is desperately lonely. It's been seven years since her father disappeared, and while her mother is determined to move on, Diamond can't distance herself from his memory. When Diamond receives a letter from a relative she has never met, she unearths long-buried secrets of her family's past and discovers a legacy she never knew she was missing. The more she learns, however, the harder it becomes to reconcile her old life with the one she wants to lead. So begins an epic story spanning the twentieth century that reveals a much larger picture of prejudice and love, of devotion and abandonment - and will change Diamond's life forever.
