Henrietta Rolland reigns as queen of the London Season, winning men's hearts and women's envy with her beauty, charm, and wit - until she discovers that a notorious rake, Jason Cavander, the Marquess of Oberlon, is responsible for the death of her brother Damien at Waterloo. Determined to avenge her dead brother, Henrietta disguises herself as the fictitious Lord Harry Monteith, hoping to fool Cavander and challenge him to a duel. Needless to say, her plan does not unfold quite the way she has anticipated.
