Raithe, the God Killer, may have started the rebellion by killing a Fhrey, but long-standing enmities dividing the Rhune make it all but impossible to unite against a common foe. And even if the clans can join forces, how will they defeat an enemy whose magical prowess makes the Fhrey indistinguishable from gods?

The answer lies across the sea in a faraway land populated by a reclusive and dour race who feels nothing but disdain for both Fhrey and mankind. With time running out, Persephone leads the gifted young seer Suri, the Fhrey sorceress Arion, and a small band of misfits in a desperate search for aid—a quest that will take them into the darkest depths of Elan. There, an ancient adversary waits—an enemy as surprising as it is deadly.
