Abducted by a band of renegade Scots, Highland gypsy Tasara Faas doesn't hesitate to blacken her rescuer's eye when the charming duke attempts to steal a kiss. Afterward, she learns she's the long-lost heiress Alexandra Atterberry and is expected to take her place among the elite society she's always disdained.
Lucan, the Duke of Harcourt, promised his gravely ill mother he'd procure a wife by Christmastide, but intrigued by the feisty lass he saved in Scotland, he finds the haut ton ladies lacking. Spying Alexa at a London ball, he impulsively decides to make the knife-wielding gypsy his bride despite her aversion to him and her determination to return to the Highlands.
The adversary responsible for Alexa's disappearance as a toddler still covets her fortune and joins forces with Harcourt's arch nemesis. Amidst a series of suspicious misfortunes, Lucan endeavors to win Alexa's love and expose the conspirators, but only succeeds in reaffirming Alexa's belief that she is inadequate to become his duchess.
