My Enemy, My Earl by Tammy Andresen

Fleeing London, and scandal, Lady Clarissa Burton runs directly into the wife-hunting Earl of Dumfries while traveling on a rutted Scottish road. She wanted peace in Scotland, not a tall and brooding laird who makes her forget that handsome lords are nothing but trouble.

Having spent years of his life fighting English wars, Ewan McDougal, Earl of Dumfries, wants nothing to do with England, or its people, for as long as he lives. He wants a nice Scottish lass to warm his bed and raise a family. So why can’t Ewan stop thinking about Lady Clarissa’s pouty lips or her curves made for a man’s hands? And what happened to her in London that has her running scared?
