The Lady and the Laird (Scottish Brides) by Nicola Cornick
An Indecent Proposal
Bluestocking darling and secret scribe Lady Lucy MacMorlan has no interest in marriage. Putting herself second to a man is definitely not for her. Instead, she makes a profit from matchmaking others and her clandestine love letters are the hushed talk of Scottish society.
Except now her talent is causing distress-one of Lucy's more provocative letters has just cost Robert, Marquis of Methven, his much-needed betrothal. It doesn't help that Robert is a bitter enemy of the MacMorlan family with a personal vendetta against Lucy. His revenge? She must marry him or he will wage war on what is left of her good reputation...
