They call him the Devil Earl - a scoundrel and accused murderer who grew up on the violent London streets. A proper young lady risks more than her reputation when consorting with the roguishly handsome Lucian Langdon, but Lady Catherine Mabry believes she has no choice. To protect those she loves, she would do anything-even strike a bargain with the devil himself. Lucian desires respectability and a wife above all else, but the woman of his choosing lacks the social graces to be accepted by the aristocracy.

They are England's most eligible bachelors, with the most scandalous reputations. But for the right woman, even an unrepentant rogue may mend his ways…Lady Grace Mabry's ample inheritance has made it impossible for her to tell whether a suitor is in love with her…or enamored of her riches. Who better to distinguish beau from blackguard than her notorious childhood friend, the Duke of Lovingdon? With no interest in marriage, Lovingdon has long lived only for pleasure. He sees little harm in helping Grace find a proper match.

After six unsuccessful seasons, Miss Minerva Dodger chooses spinsterhood over fortune-hungry suitors. But thanks to the Nightingale Club, she can at least enjoy one night of pleasure.

A lady does not smoke cheroot. She does not ride astride. She does not fence or attend duels. She does not fire a pistol, and she never gambles at a gentlemen's club. Lady Calpurnia Hartwell has always followed the rules, rules that have left her unmarried - and more than a little unsatisfied. And so she's vowed to break the rules and live the life of pleasure she's been missing. But to dance every dance, to steal a midnight kiss - to do those things, Callie will need a willing partner. Someone who knows everything about rule-breaking. Someone like Gabriel St. John, the Marquess of Ralston....
