Captive by Joan Johnston

She was a gorgeous rebel.

Defying all the rules, daring to speak her mind, Charlotte Edgerton declared her independence before she even entered the Earl of Denbigh's home. Her new guardian immediately made her a prisoner in her own room—until she agreed to learn the lady-like arts. Furious, she complied. Anything to buy her freedom from Denbigh. She'd even marry a man she didn't love to get away from her domineering guardian. In fact, love was the furthest thing from her mind...

He was the Earl who vowed to tame her.

Lionel Morgan, Earl of Denbigh, had been betrayed at the altar by another woman and vowed that no female would ensnare him again. Then Charlotte Edgerton burst into his life. Denbigh wasn't prepared for this headstrong American—or the passions she inspired on first sight. He knew only that he had to civilize her, present her at court, and Almack's, and then marry her off to the highest bidder. It wasn't until he nearly lost her that he realized the truth: She'd somehow reversed their roles and become the captor of his heart
