Lady Genevieve St. Giles yearns for adventure, something more exciting than her staid, proper life. When she reads about an illicit house party hosted by the Duke of Argyle, she finds the solution to two of her problems—boredom and being consistently overlooked by the duke. Hopefully, with her attendance at this house party, she will finally gain his notice. When she succeeds, it doesn't go quite as she'd hoped. But determination runs strong in her family, and she will stop at nothing to gain his loyalty—and his love.
Cortland Beaumont, the Duke of Argyle, is a loyal member of the Wayward Duke's Alliance. When Lady Genevieve stumbles into Cortland's manor after stealing her grandfather's invitation, coincidentally, the founder of the alliance, Cortland fears that his membership will be revoked if her reputation is ruined. Thus, he approaches the lady with a proposal, which she firmly rejects.
A game of cat and mouse ensues, and although Cortland tells himself he's not chasing after Lady Genevieve because he's infatuated with her, his heart soon convinces him otherwise.
