The Doxy and the Duke (Second Chance Manor #6)
Caroline Lee

Until the day she takes her son swimming and meets a handsome and mysterious stranger, enjoying the water with his son. What harm could there be in having some fun with the man who refuses to tell her his full name or rank? And if he thinks the worst of her…well, that could be fun too!
The Duke of Cashingham has no time for frivolities, but he’s given his heir, Matthew, his word that he’ll make an effort to find a second wife. Thus, he has made a point of attending the Fangfoss affair to meet each eligible lady, and has been disappointed. But when he meets an intriguing—and obviously easy-virtued—Scottish lady by the river, he sees no harm in suggesting an informal liaison.
But the more time Cash spends with her, the more he realizes Raina is exactly the sort of woman he wants for a wife. Too bad a Duke can’t marry his doxy…
It’s up to mischievous Ewan and studious Matthew to convince their parents not only are they in love, but they have a chance at a Happily Ever After…before the end of the house party!
