Synopsis: From the back cover of the Popular Library first edition: "Alexa, princess of Byzantium was destined to rule alongside her devoted brother Marric. But evil forces, casting dark magic up her made her betray him. Thus Marric fell under attack, the usurper seized the throne and, by means magical and moral, vanquished Alexa. Rescued by warrior allies, Alexa has been taken to a strange northern land. Certain of Marric's death, she is consumed by guilt- and terror. Even from afar, the usurper's power reaches out to ensnare her. Savage dreams torment her nights, prophecies of doom haunt her days, and fiery magic runs wild within her soul. Alexa's only hope lies among the Druids of the distant Misty Isles. They alone can purify her of the darkness that taints her and teach her to use her powers well. But Alexa must learn more than the secrets of the Druids. For in her hands and heart lie the survival of Penilyn itself... and the fate of Byzantium."
