On a Wild Night(Cynster‪)‬

Where are all the exciting men in London?
After spending years in the glittering ballrooms of the ton, Amanda Cynster is utterly bored by the current crop of colorless suitors. Determined to take matters into her own hands, one night she shockingly goes where no respectable lady ever should, but where many an intriguing gentleman might be found.
But titillating excitement quickly turns to panic when Amanda discovers she's quite out of her depth. She looks around for help—and is unexpectedly rescued by the Earl of Dexter. Lean, sensuous, and mysterious, he has delayed re-entering society, preferring instead a more interesting existence on its fringes.
He's the epitome of the boldly passionate gentleman Amanda has been searching for, but although his very touch makes it clear he's willing to educate her in the art of love, Amanda has to wonder if such a masterful, lionized rake can be sufficiently tamed into the ways of marriage.
