The duke's rules of engagement
(Book)

For fans of Elizabeth Hoyt and Sarah MacLean, London's best matchmaker must ensure a complicated duke marries a wealthy wallflower. Too bad the duke is falling in love with her instead.

"Joanna Porter loves being one of London's hottest up-and-coming matchmakers. But her heavenly vocation is about to turn into a nuptial nightmare--thanks to the Duke of Crestmont. He's as handsome as he is insufferable and obsessed with all things proper. Matching him would cement Jo's status as England's greatest matchmaker. Except, of course, the impossible-to-please duke refuses all of her most eligible ladies...confirming his status as a complete and utter pain in her petticoats. The Duke of Crestmont can't believe he needs a matchmaker--let alone this spitfire of a woman whose kissable mouth and dancing, impertinent gray eyes tease him ruthlessly. But the people of his estate are counting on him to find a duchess. A proper lady with a flawless pedigree and immaculate deportment. So why can't he stop himself from wanting his pert, lively matchmaker...instead of the perfect duchess? Now the entire ton is watching as this determined, audacious matchmaker takes on the most powerful man in London in USA Today bestselling author Jennifer Haymore's lively new Regency romp. And this show might just be the most outrageous one yet..."--,Publisher's description.
