The Duke starts a scandal / Sophie Jordan.

A gentleman never dallies with the help, but the new Duke of Penning is no gentleman in this steamy fourth and final book in The Duke Hunt series by New York Times bestselling author Sophie Jordan. A duke with secrets. Lucian, the newly minted Duke of Penning, has much to prove--to himself, his family and the ton. Craving spotless respectability, he must find an aristocratic wife. Unfortunately, he can't keep his eyes--and thoughts--off his deliciously distracting housekeeper. Such a dalliance can only mar the facade he's constructed to protect his sisters' future from the demons of his past...but this fiery passion is a temptation he cannot resist. While Susanna may not the bride he needs, she is everything he desires. A woman with a past. As the housekeeper to one of the grandest estates in England, Susanna Lockhart has worked determinedly to become all that is proper and efficient, and she never steps over the line. Romance is an indulgence for the upper class, not for her--and most especially not with her employer. But every smoldering glance from the surly, handsome duke calls to the long-buried reckless wanton inside Susanna. A love between them can never be, but will Lucian and Susanna risk being together... Even if it starts a scandal... --
