So when the brooding English knight accidentally came across her in a moonlit garden, he was both surprised -- and delighted.

But the magic of that enchanted moment is soon shattered by cold reality: Nesta is not the woman he is to marry, but her sister. Of all the women Marcus might desire, none could be more dangerous than the wild and tantalizing Welsh witch with secret ties to both rebellion and king. For Nesta, no one could jeopardize her plans more than a man who would know the secrets of both her heart...and her body. Yet the course of their lives -- and the destinies of their two nations -- will be forever altered as they defy everything to surrender to the most daring seduction of all....
