Someone has been stealing Christmas's joy, and there's only one clue to the culprit, a single shamrock. Kris volunteers to investigate St. Patrick's Day. His cover: an ambassador from Christmas to foster goodwill. What could go wrong? Everything, it seems. Because Prince Lochlann Patrick, Crown Prince of St. Patrick's Day, happens to be the mysterious student that Kris has been in a small war with at Cambridge. They attempt to play nice for the tabloids, but Kris can't get through one conversation without wanting to smash Loch's face in, he's infuriating, stubborn, loud, obstinate, hot.
