Age of swords
(Book)

"Raithe, the God Killer, may have started the rebellion by killing a Fhrey, but long-standing enmities dividing the Rhunes make it all but impossible to unite against the common foe. And even if the clans can join forces, how will they defeat an enemy whose magical prowess renders them indistinguishable from gods? The answer lies across the sea in a faraway land populated by a reclusive and dour race who feel 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, as fearsome as it is deadly."--Amazon.com.
