Lady Augusta Penworthy is in dire straights. Her father has spent every last coin, and she and her sisters cannot even afford coal. One chance encounter and a torn gown changes everything. While one might think a sudden marriage to a wealthy lord a relief if that marriage is to the Duke of Blacktower, one would be vastly mistaken. For no young lady wishes to be that infamous rake's bride.

Lady Ludmilla Windmere is mortified. The spinster extraordinaire has fallen in love with her best friend, and that cannot be. The problem? She hasn't met him. Not once. For they have only ever corresponded by letter. When she sets out to uncover his identity, her world shatters. For Addy turns out to be none other but London's worst rake. Adrian St. Addington is perturbed. The rakehell extraordinaire is developing a marked tendre for a spinster, and that cannot be. The problem? She might be mistaking him for someone he is not. Or, what is worse, know precisely who he is.

Thea Knight loves a spot of mischief. She especially loves her current mischief: masquerading as her sister, while finalizing her scheme to expose the dastardly knaves whose lies ruined her life. Then big, bad-tempered Lord Luxborough upends her game by maneuvering her into marriage. But it's her sister’s name on the license, so the marriage won’t be valid. Thea’s idea? Keep pretending to be her sister until she can run away.

Trevor Hunt, the Duke of Ridgely, has been called many things, most of which are true. Reviled by his family, hated by many, he's earned his reputation in the seedy streets of London and more than his fair share of bedchambers.

Edward Stanhope, the icy Duke of Thornfield, likes his life in a certain order. Give him a strong drink, a good book, and his dog for company, and he’s content.

So, of course, damn it all, that’s when Edward’s aunt walks in and, thereafter, announces Miss Georgiana Bly as the future Duchess of Thornfield.
