Molly. Edwardian Candlelight 2

The second book in M. C. Beaton's charming Edwardian Candlelight series. She had dared to turn a cold shoulder on London's prize catch. She was a precocious American upstart who thought beauty, brains, and bravery were enough to conquer London society. Well, he'd show her! Nobody publicly (or privately!) spurned Lord David Manley, the most eligible bachelor in town. He was determined that soon she'd be trembling in his arms, desperately in love with the man she had dared to mock.
David Manley always got his way, and Miss Molly Maguire presented a challenge he couldn't resist! But Lord David had never met anyone quite like this headstrong heiress who fought like the devil, looked like an angel, and had all of London society dangling on a string. The Edwardian Candlelight Series chronicles young, passionate girls who come to understand the nature of true love despite overwhelming odds.
From a penniless pauper, a stenographer, a governess to an accused murderess, these ladies in love overcome incredible odds with grit and sophistication to find and keep true love.
