When a masked stranger at the Christmas masquerade helps Isolde avoid her suitors, she is grateful—until she realizes he is the son of the neighboring family, come to steal a pendant their mothers have feuded over for years.Gawain Burke sneaked into the Christmas masquerade with one goal: to retrieve the pendant that rightfully belongs to his mother. But his chivalrous instincts come to the fore, and protecting Isolde from lecherous men becomes his primary concern. He's not a suitor for her hand. She has sworn never to marry again. They'll just work together to return the pendant and stop the feud. But neither of them reckons with the ghost, who has a far better ending in mind.
