Two royal princes, one fake competition ? but will it be trick?or treat? Coal might be the Prince of Christmas but, honestly, he?d rather skip it this year. Wouldn?t you when your father, the reigning Santa, has turned it into nothing more than the family?s latest PR stunt? But even Coal couldn?t predict his father?s latest move ? announcing Coal?s engagement (much to his surprise) to his best friend, Princess Iris of Easter, to unite their families for the perfect holiday photo moment. When a rival arrives to challenge for the princess? hand, Coal is suddenly face to face with a past mistake: Hex, the deliciously handsome Prince of Halloween. As they spend more and more time together, Coal finds himself drawn to Hex. But scuppering Santa's plans and falling for Christmas's biggest rival would be a complete disaster... wouldn't it?
