Lythande by Marion Zimmer Bradley. mass_market edition. ISBN: 9780886771546.

Lythande was pledged by sword and spell to fight the forces of chaos. A Pilgrim Adept of the Blue Star, Lythande had mastered all the true magics of the world. But the power of an Adept was always bound to a Secret, and whoever discovered this sorcerers Secret could steal away the blue Star power, leaving the Adept defenseless, fit only for death. And Lythandes secret was perhaps the most dangerous of all, setting the mage apart from all humanity, forcing Lythande to war against spell beast, sorcerer, thief, swordsman, and the magic of the gods themselves.
