When Queen Seraphina learns that her late daughter left behind a five-year-old girl, she rushes to a convent to bring her granddaughter home. But her ambitious cousin Edmund tricks her into accepting Sophie as the royal heir. The real princess, Elowen, is mistaken for an unwanted orphan and brought to the palace out of pity. While Sophie enjoys a life of luxury, Elowen continues to suffer humiliation. Yet Seraphina can't ignore how much the little girl resembles her late daughter—even down to her smallest habits. Then Elowen sees a royal portrait and cries, "Mommy!" The Queen begins to suspect a terrible mistake. Desperate to protect his claim to the throne, Edmund fabricates records, tampers with DNA evidence, and eventually kidnaps Elowen. Seraphina finally uncovers the conspiracy, rescues her real granddaughter, and restores her rightful place in the royal family.
