Devon Ravenel, London's most wickedly charming rake, has just inherited an earldom. But his powerful new rank in society comes with unwanted responsibilities...and more than a few surprises. His estate is saddled with debt, and the late earl's three innocent sisters are still occupying the house - along with Kathleen, Lady Trenear, a beautiful young widow whose sharp wit and determination are a match for Devon's own.

In the service of England's spymaster (well, his niece, but surely he'll appreciate the help), Miss Mary Wilson is on a mission to uncover a treasonous plot. Though her only clue leads to the debaucherous secret society of the marquess of Hartford, a lifetime of being overlooked should ensure her access to all of the gossip her assignment will require. There's just one problem: Mary is due to find a husband this season, and her aunt Elizabeth, the Viscountess Hood, is determined to see her niece shine bright.

Jasper Sutton—London’s most dedicated scoundrel—needs a wife, and he needs one quickly. He needs one yesterday, in fact. His requirements are precise: she must be capable of mothering the wild twin daughters who have unexpectedly appeared in his life, and so must possess the patience of a saint and the understanding of an angel. Better still if she is plain and has no expectation of a true marriage. He is not about to reform his ways.

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....

Lord Nathaniel Harte, the disagreeable duke of Beswick, spends his days smashing porcelain, antagonizing his servants, and snarling at anyone who gets too close. With a ruined face like his, it's hard to like much about the world - especially smart-mouthed harpies (with lips better suited to kissing than speaking) who brave his castle with indecent proposals. But Lady Astrid Everleigh will stop at nothing to see her younger sister safe from a notorious scoundrel, even if it means offering herself up on a silver platter to the forbidding Beast of Beswick himself.
