The evil Lords of Zhev'Na kept Gerick captive for months. Although his parents rescued him, he remains tormented by his experience-and mistrusted even by those who love him. Accused of treason, Gerick flees and takes refuge in a magical realm full of outcasts, where he will discover how to use his own magical talent-soul weaving-to save his people from Zhev'Na.
