Respect for Christmas by Grace Burrowes

Henrietta Whitlow is leaving behind the life of a very successful courtesan in hopes of making peace with her family in the shires. Michael Brenner’s family all but ignore him, despite his shiny new baronial title, and his errand along the Oxford road isn’t half so benign as Henrietta’s. While trying to settle a debt of honor involving Henrietta, Michael instead loses his heart and comes to understand the true meaning of holiday spirit.
