The Marquess’ Saving Grace by Ella Edon

A kiss has never been so depraved as this one…

Grace Baker was always dreaming of being a noble lady for one night, instead of what she really is; a simple maid. The only way to fulfill her wish is to sneak into a masquerade ball. Everything is unfolding according to plan, but then a problem arises. She is seduced into a kiss by the handsomest nobleman, but ashamed of her lie, she flees.
Alexander Wentworth, the painfully brooding Marquess of Surrey, is astonished when he discovers that the lady who occupies his mind is a lowly maid. His sense of honor cannot accept her foolery. When Alex confronts her, the last thing he expects is to find himself tempted to dishonor both of them even more.
Unfortunately, Grace is not strong enough to resist ruination. After all, being the mistress of a Marquess is not the worst thing that can happen to a girl with no prospects.
Until a discovery, so shocking, will come to light that will definitely send both of them straight to hell…

She is his missing piece, but the puzzle reveals a nightmare…
