Will she give up her twenty-first century life to remain in the past with Nicholas? Baron Nicholas de Montclair thinks he needs help protecting his son from his evil brother-in-law. But when he brings Julie back to his time, he finds it's a year earlier than he left and there's no child to protect. He and Julie are forced to overcome sieges, abductions and pregnancy with the aid of the amethyst amulets. Then Julie is forced to return to the future. Has he lost forever the woman he's come to love?
