A Countess For Christmas Vol.1: Harlequin Comics

Emma takes a job as a maid at a high-class party to help pay off her late father’s debts. Once upon a time these parties had been her life. Caught up in the spell of nostalgia, Emma makes a disastrous mistake on the job. Her boss tries to take advantage of her vulnerability and forces himself on her.
That is, until Jack Westwood, the new earl of Redminster, intervenes. He claims Emma is his wife to scare off her boss. But his claim isn’t far from the truth. It’s been six years since Emma has seen Jack—her estranged husband—and now he’s back in the picture.
