Shapeshifting Prince Dolph is engaged to two women he doesn't love and dreads the consequences of choosing either — until the kidnapping of a young centaur foal gives him something more urgent to focus on. Only a guileless visitor from another world seems to know where the child has gone, and Dolph's hunt for her becomes a way of avoiding his own heart. The thirteenth Xanth novel turns an arranged-marriage dilemma into a rescue quest.
