Legacy of Kings — C.S. Friedman

The young peasant woman Kamala has proven strong and determined enough to claim the most powerful Magister sorcery for herself-but now the Magisters hunt her for killing one of their own. Her only hope of survival lies in the northern Protectorates, where spells are warped by a curse called the Wrath that even the Magisters fear. Originally intended to protect the lands of men from creatures known only as souleaters, the Wrath appears to be weakening-and the threat of this ancient enemy is once more falling across the land.
