Twenty-One Nights — Ariel Atwell

They called her Lady Perfect...
Penelope Cavanaugh, widow of the sixth Marquess of Huntley, is regarded by London society as the perfect wife and mother. With her upcoming wedding to the fabulously wealthy, but oh-so proper Duke of Kirwood, she'll soon be the perfect duchess. But the accidental discovery of an old book offering lessons about the pleasures to be had in the bedchamber sparks Penelope's desire to experience true passion before settling down into marriage again. Who can Lady Perfect trust to be her tutor?

A rake without redemption...
Reviled for gambling away his family's fortune, Viscount Weymouth is just days away from debtor's prison when he receives a mysterious summons and a most improper offer. In exchange for teaching her lessons in sensual pleasure, Penelope will give Weymouth the money he needs to reclaim his heritage. But will twenty-one nights really be enough to satisfy their need for each other?
