Defiance of the Fall – serial

Zac was alone in the middle of the forest when the world changed.

The whole planet was introduced to the multiverse by an unfeeling System... or God. A universe where an endless number of races and civilizations fought for power and dominion. Zac finds himself stuck in the wilderness surrounded by deadly beasts, demons, and worse. Alone, lost and without answers, he must find the means to survive and get stronger in this new cut-throat reality.

With only a hatchet for his weapon, he'll have to seek out his family before the world collapses... or die trying.
