Auring's Wrath (Leviathan Book 1) by Justin DePaoli

SPFBO6

The lands of Covecus bleed magic and power, but its storied civilizations have been long forgotten, buried under the inexorable march of a deadly blight. Now, the scourge looms before the last peoples of Covecus, whose hope depends on the rise of a hero. And there's never been one of those. Until now. From the north, a young warrior seeks revenge for his imprisoned parents. He would take up arms against the blight itself to free them. From the south, a huntress desires more than the raw power of sorcery she possesses. She knows the scourge has a weakness, that it's alive. That it can be killed. As secrets are unearthed and godless beasts descend upon the last living civilization, two unlikely heroes will rise. Or a world will fall.
