What Once Was One (The Passage of Hellsfire, Book 2) - Marc Johnson - Bog

In the land of Northern Shala, the dark wizard Premier raised an army of foul creatures from the Wastelands and led them against the ancient guardian city of Alexandria. Hellsfire, a young farmhand turned apprentice wizard, defeated Premier and saved Alexandria, but not before the battle claimed his mentor's life.
Hellsfire, now a full-fledged wizard, must finish what he started by hunting down Premier and seizing the source of the wizard's dark power and corruption-the Book of Shazul. He must travel deep into the Wastelands, through Premier's home territory, dodging the scattered remnants of a defeated army lusting for blood and vengeance.
But beating in the heart of the Wastelands is an ancient power more dangerous than Premier or his creatures-and it's been waiting for Hellsfire for a thousand years. It will force the young wizard to make a devastating choice-one that could change the course of history not only for Alexandria and the Wastelands, but for all of Northern Shala and the lands beyond. And to save his homeland, Hellsfire may have to lose the person he loves the most.
What once was one, will then be two, and never again be whole...
