Fairest of Them All — Teresa Medeiros

She was rumored to be the fairest woman in all of England. But Holly de Chastel considered her beauty a curse. She had already turned away scores of suitors with various ruses, both fair and foul.

Suddenly she found herself in the possession of this mysterious stranger, ensconced in his castle, and forced to keep up her carefully planned illusion. Why did this electrifyingly passionate male, who could have any woman he wanted, desire a homely bride - and what would happen when he learned he'd been tricked? By the time Holly found out, it was too late to avoid the searing fires of passion - and the dark curse of Gavenmore...
