It is to be The Match of the Season. At least, that’s what Lady Carlotta Merritt, sister to the cool and aloof Duke of Cashingham, has been told repeatedly by her mother. The Dowager is beyond thrilled about her daughter’s engagement to Society’s most eligible bachelor, Lord What’s-His-Face. Carlotta, on the other hand, would much rather be gallivanting around her brother’s Yorkshire estate, falling out of trees or fishing in the streams or reading one of her naughty books in the shade on a summer day. But her mother has made it very clear that she’s to behave herself, as befitting the sister of a duke, and Carlotta has been trying, honest. But when Mother is called up to Scotland, she invites Carlotta and her fiancé to follow…sans chaperone. That’s when her brother volunteers his own brother-in-law—the illegitimate Scotsman with a charming grin, a wicked reputation, and battered hands which make Carlotta think all sorts of wicked thoughts—to tag along.
