An alternate cover edition can be found hereThe Emerald flew across the seas, carrying the pirate Pagan -- despised by the ton, whose riches he plundered, and beloved by the poor, whose plight was eased by his gifts. The Marquess of Cainewood vows to hunt down the pirate wretch in revenge for his brother's death. But when Jade, an enchanting vision of rippling red hair and eyes of jewel-green, appears at his door to beg desperately for his protection, the Marquess agrees to keep her safe from the villains who want her dead. Jade is infuriating, exasperating, and gorgeous; Caine is noble, strong-willed, and powerful. No woman has ever befuddled him so, nor so deeply aroused his desire. But as Jade answers his knowing caresses with an innocent, wild abandon, they are drawn into a web of treachery that will test the very heart of their love!
