Cynders & Ashe by Elizabeth Boyle.
This is a short story (less than 10,000 words) that was originally published in The Mammoth Book of Regency Romance.
Five years ago, Ella Cynders was the companion to a young lady bent on following her heart. While her employer was eloping, Ella had to stand in her place at the masked ball where Viscount Ashe was looking for a wife.
While there, Ella and the Viscount find a passion that is unforgettable. Unfortunately, Ella is forced to leave the ball before the unmasking.
Viscount Ashe has spend the last five years looking for the love of his life. If he doesn't find her, he will have to choose another. Will he find her at this year's ball?
Ella finally has a way to get into the Ashe ball again. Will she find the man who stole her heart?
For such a short story, it was a good read. Although this is a typical Cinderella story, Boyle has put a nice twist to it. I would have loved more to the story, but knew it would be short going into it.
