Book III of The Chronicles of Deryni. For centuries the Deryni - the most powerful of sorcerers - had been outcasts in the semi-Christian kingdom of Gwynedd. Now with the boy king Kelson Haldane on the throne, the priesthood of the Eleven Kingdoms feels its control seriously threatened. Kelson's half-Deryni ancestry was revealed at his coronation, causing the archbishops to busy themselves with treachery. They plot to excommunicate Kelson and split his kingdom by the creation of civil war, with royalists against rebels. Cover art by Darrell K. Sweet.
