Many years have passed since the Occitanian knights killed Richard the Lionheart in a courageous battle to keep the Blue Flamesparked at the moment of Christs deathfrom falling into the wrong hands. Now it is in danger once again, as enemies from the north draw near. In the midst of this looming battle, lifelong friends Raimon, son of a Cathar weaver, and Yolanda, daughter of a Catholic Count, are falling in love. But a new religious crusade is about to begin, setting boy against girl, family against family, neighbor against neighbor, south against north. Though many seek to possess the Blue Flame, only one person is destined to wield its power to save the people and the sovereignty of the Occitan.
