Rhys Sheffield, the Duke of Worthington, has bet his friends an ungodly sum of money that despite his loftiness, he can pass himself off as a servant at the house party of the Season. But when his clever ex-flame arrives and recognizes Rhys in the stables pretending to be a groomsman, she realizes it's the perfect opportunity to pay him back for breaking off their engagement. The lovely Lady Julianna Montgomery may be the only young woman at the house party who's not in the market for a husband. She's quite happily engaged to a marquess, thank you very much, and scarcely remembers the pain of being callously tossed over by the Duke of Worthington nearly two long years ago-till now.
