The Forgotten Gods by Jeff Pantanella
What could be worse than a cosmic, world destroying, vampire hungry to drain the Mortal Realm of all life? How about two of them?
The stakes rise to cataclysmic proportions and with the Seven Heavens and Abyss preoccupied with internal war, defense of the Mortal Realm falls to the Ever Hero, a broken and recluse man.
Six years have passed since the defeat of Sekka at the hands of the Ever Hero. The Heavenly Host has departed, leaving the lands a charred, ash-ladened dystopia. Kasai Ch’ou has returned to the ruins of Ordu, seeking solace, but finding none.
Enter Cyrus Wraith, a mysterious Master Monk of Lost Symmetu, who promises to guide the famed Ever Hero back to the elusive Boundless and help him rebuild the Four Orders of Aetenos. But Cyrus has a hidden agenda, and his obsession with the ancient staff, Ninziz-zida, quickly becomes problematic.
Kasai must rekindle the fire in his soul but in the process, starts down a path that will force him to do the unthinkable to the one person he holds most dear or watch helplessly as the Three Worlds are consumed, literally.
A perfect fit for epic fantasy fans of Brandon Sanderson, Robert Jordan, Michael J. Sullivan, Edward W. Robertson, Patrick Rothfuss, and Michael Wisehart.
