Bedding the Heiress (Cameron Sisters, 4)

When a loathsome rake steals one of her most cherished family heirlooms—and nearly her virtue as well!—Francesca Dunroy devises the perfect plan to put him in his place. At a ball being held in her honor—she didn't "take" in her first season, now her family is determined to get her a match in her second—she'll offer him a clandestine kiss sure to convince him to return what is rightfully hers. But in the dark hallways surrounding the ballroom, Francesca makes a terrifying mistake. She seduces the wrong man!
The recipient of Francesca's caresses is none other than Justin Maddox, London's newly titled duke and most eligible bachelor. A defiant Scotsman who disdains London society, he's sworn to steer clear of the ladies of the ton, but he can't escape the memory of Francesca urgently pressing her lips upon his . . . and neither can she. But when a shocking and dangerous secret from Justin's past resurfaces, the couple will have to risk tattered reputations and treacherous enemies to nurture what has quickly become true love.
