There was a king - King Arthur of Camelot

There was a knight - Sir Nicholas the Dragon

There was a wager that each swore he would win . . .

Lady Noelle has no intention of marrying just to save her family's castle. She feels nothing for Sir Gavin, the man who will become her husband on Christmas Day. Then she spies Camelot's newest knight, the notorious Sir Nicholas the Dragon, a champion as renowned for his prowess in the beds of Camelot's maidens as for his skill in battle. Noelle's heart has found the man she longs for, even as her hand is promised to another.

Christmas may never come to Camelot.
