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.

Annabelle's fondness for exploring the outer limitations of propriety does not imply that she has no desire to find someone in her life strong enough to take her in hand when she has gone too far. Jumping onto the wrong train, and then travelling alone with a handsome stranger to a house party is bad enough behaviour to get her into all sorts of trouble with the people who are putatively in charge of her. In this man's company, can Annabelle maintain the image of the demure young lady that society demands?

Widowed rancher Heath Wolfe worries he's making a big mistake by bringing Willow McAllister home to his ranch. A known troublemaker around town, she can't seem to keep a job or avoid skirmishes with the law, so the town marshal implores Heath to help. While Heath agrees to employ Willow, he certainly won't allow misbehavior, and he's even prepared to take the willful young lady over his knee for a sound spanking if warranted.

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. But battling deadly foes and irate husbands failed to prepare the duke for the most troublesome role he's played yet: guardian to one maddening hoyden.

Rumors abound about the rakish Viscount Rochford, a man who’s left a trail of wailing hearts in his wake. With a reputation for jilting society women, the ton can scarcely believe he is ready to settle down and wed. Neither can Miss Penelope Stratton. With her enviable looks and sizable dowry, this shy country girl finds herself with an impressive list of suitors. Yet against all her better judgment, she is drawn to the one man least suited to matrimony; a notorious man with a scandalous past.
