Seven years ago, Rose Balfour had to cut her first season in London short after pushing Lord Alton Sinclair into a fountain. She believes the past to be behind her, even when her godmother, the Duchess of Roxborough, who is also Lord Sin's favourite aunt, invites Rose to spend the season with her in Edinburgh. Lord Sin, however, has been simmering with his need for vengeance ever since he last saw Rose. When she accepts the Duchess's invitation, he puts his plan in motion-to humiliate Rose like she once humiliated him. What he didn't count on was how much fun it would be to spar with her, or on falling in love with her.
