Curse of the Mistwraith — Janny Wurts

It began with a Mistwraith that smothered all the world in fog and dampness, and followed with a war that upended order and overthrew the rule of the High Kings. Now after five long centuries, the only power that can challenge the Mistwraith's stranglehold is split between two princes. Arithon, Master of Shadows, able to weave darkness to his will. And Lysaer, Lord of Light, is sworn to justice. Driven apart by distrust and opposing convictions, the half-brothers must master their inborn enmity and meld their powers into a unified force. Should they fail, the Mistwraith shall ensnare them in strife and bloodshed for its own ends. No single character will emerge unchanged.
