No one knows what happened to the little Princes of the Tower. That's what Dane, Paige, and Jack are told when they start working on a medieval documentary for Dane and Paige's filmmaker father. But then an ancient medallion transports them back to the fifteenth century and gives them a chance to discover the truth about the mysterious disappearance of young King Edward the Fifth and his brother Richard, Duke of York. But they'd better be careful. The princes are definitely in danger, and the person responsible for their disappearance just might decide that their new friends should disappear as well.
