He can’t keep his eyes off Sophie, and to get her he breaks his ironclad rule against gambling.

Charlotte Griffolino knows a rake when she sees one - and the man her niece longs to marry most definitely qualifies. Stuart Drake is handsome, charming - and penniless.

With a Viscount title in his future, Stuart expects it shouldn't be difficult to marry an heiress. Still, once he meets Charlotte, how hard will it be to charm her? Quite, actually. Now Stuart has only one option: to take revenge on her through seduction.

Luckily, she has the perfect plan.... She'll impress the ton by simply announcing she is engaged to the reclusive and mysterious Duke of Thornton, Alexander Masters, and secure strong matches for her sisters. No one has heard from the duke in years. Surely he'll never find out before her sisters' weddings and she can go back to her own quiet life.

Charlotte Langley has always been the prudent middle sister, so her family is not surprised when she makes the safe choice and agrees to wed her childhood sweetheart.

Hugh Philemon Ancaster, seventh Duke of Ripley, will never win prizes for virtue. But even he draws the line at running off with his best friend's bride. All he's trying to do is recapture the slightly inebriated Lady Olympia Hightower and return her to her intended bridegroom.

In his place turns up his base-born brother Mason Vawdrey. And dark, forceful Mason is no one's puppet.

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. 

It was whispered all through London Society that Ian Mackenzie was mad, that he’d spent his youth in an asylum, and was not to be trusted - especially with a lady.

Yet Beth found herself inexorably drawn to the Scottish lord, whose hint of a brogue wrapped around her like silk and whose touch could draw her into a world of ecstasy. 

By all accounts, Simon Basset is on the verge of proposing to his best friend's sister - the lovely and almost-on-the-shelf - Daphne Bridgerton.

And as for Daphne, surely she will attract some worthy suitors now that it seems a duke has declared her desirable. But as Daphne waltzes across ballroom after ballroom with Simon, it's hard to remember that their courtship is a sham. 

Cassandra DeWitt has seen her husband only once - on their wedding day two years earlier - and this arrangement suits her perfectly.

Why, he’ll never even know she is there. Until he shows up in London too, and Cassandra finds herself sharing a house with the most infuriating man in England. Joshua DeWitt has his life exactly how he wants it. He has no need of a wife disrupting everything.
