Against the Wind by Regan Walker

Can one night of passion lead to love?

Sir Martin Powell, a spy for the Crown in France, returns to London, thinking to indulge in a night in London’s most exclusive bordello. But the next morning the auburn-haired beauty he knows only as “Kit” has disappeared. Their one night of passion has him searching for her in all of London.
Certain she has killed her lecherous brother-in-law, Katherine, Lady Egerton hides away as a governess to two young women, all the while thinking of the stranger she left behind.

Once Sir Martin finds Kit, he will steal her away to the English Midlands and into the rising winds of revolution.
