The Duke's Indecent Scandal. Indecent Dukes, #1

When he kissed her in the library, he didn't know she was his best friend's little sister. Lady Tiffany Bolton, sister of the Duke of Bolton, is painfully plain and dull. At least, that's how her brother describes her as he bemoans the necessity of finding her a husband. So the rakish Duke of Clarence can hardly be blamed when the pretty girl he kisses in the library turns out to be none other than Lady Tiffany herself.
Caught mid-kiss with the ugly duckling turned beautiful swan, Gregory is left with no choice but to announce their engagement and save her reputation. And if they want to keep Society off their backs, they're going to have to convince everyone they're deeply, madly in love. Which shouldn't be too hard, since Gregory can barely keep his hands off his beautiful, enchanting bride to be. In fact, the only thing more difficult than not falling in love with his best friend's little sister might be solving the mystery of their fathers' murders.  Indecent Dukes1.
