Welcome to Stranje House.

It's 1814. Napoleon is exiled on Elba. Europe is in shambles. Britain is at war on four fronts. And Stranje House, a School for Unusual Girls, has become one of Regency England's dark little secrets. The daughters of the beau monde who don't fit high society's constrictive mold are banished to Stranje House to be reformed into marriageable young ladies. Or so their parents think.

In truth, Headmistress Emma Stranje, the original unusual girl, has plans for the young ladies—plans that entangle them in the dangerous world of spies, diplomacy, and war.

After accidentally setting her father's stables on fire while performing a scientific experiment, Miss Georgiana Fitzwilliam is sent to Stranje House. But Georgie has no intention of being turned into a simpering, pudding-headed, marriageable miss. She plans to escape as soon as possible—until she meets Lord Sebastian Wyatt.

Thrust together in a desperate mission to invent a new invisible ink for the English war effort, Georgie and Sebastian must find a way to work together without losing their heads—or their hearts…

Can there be any greater challenge to London’s Ambitious Mamas than an unmarried duke?—Lady Whistledown’s Society Papers, April 1813

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. But the two of them know the truth—it’s all an elaborate plan to keep Simon free from marriage-minded society mothers. 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 complete sham. Maybe it’s his devilish smile, certainly it’s the way his eyes seem to burn every time he looks at her… but somehow Daphne is falling for the dashing duke… for real! And now she must do the impossible and convince the handsome rogue that their clever little scheme deserves a slight alteration, and that nothing makes quite as much sense as falling in love…

When the redoubtable Sir Horace Stanton-Lacy is ordered to South America on business, he leaves his only daughter, Sophy, with his sister, Elizabeth Rivenhall, in Berkeley Square. Newly arrived from her tour of the Continent, Sophy invites herself into the circle of her relatives. When Lady Ombersley agrees to take in her young niece, no one expects Sophy, who sweeps in and immediately takes the town by storm.

Beautiful, gay, impulsive, shockingly direct, Sophy sweeps into elegant London society and scatters conventions and traditions before her like wisps in a windstorm. Resourceful, adventurous and utterly indefatigable, Sophy is hardly the mild-mannered girl that the Rivenhalls expect when they agree to take her in. Kind-hearted Aunt Lizzy is shocked, and her arrogant stern cousin Charles Rivenhall, the Ombersley heir, vows to rid his family of her meddlesome ways by marrying her off.

But vibrant and irrepressible Sophy was no stranger to managing delicate situations. After all, she'd been keeping opportunistic females away from her widowed father for years. Staying with her relatives could be her biggest challenge yet. But Sophy discovers that her aunt's family is in desperate need of her talent for setting everything right: her aunt's husband is of no use at all, her ruthlessly handsome cousin Charles has tyrannical tendencies that are being aggravated by his pedantic bluestocking fiancée Eugenia Wraxton; her lovely cousin Cecelia is smitten with an utterly unsuitable suitor, a beautiful but feather-brained poet; her cousin Herbert is in dire financial straits and has fallen foul of a money-lender; and the younger children are in desperate need of some fun and freedom, and Sophy's arrived just in time to save them all.

With her inimitable mixture of exuberance and grace, Sophy becomes the mainstay of her hilariously bedeviled family, as a horsewoman, social leader and above all, as an ingenious match-maker. Using her signature unorthodox methods, Sophy sets out to solve all of their problems. By the time she's done, Sophy has commandeered household and Charles's horses, but she finds herself increasingly drawn to her eldest cousin. Could it be that the Grand Sophy had finally met her match? Can she really be falling in love with him, and he with her? And what of his betrothal to grim Eugenia?
