First Snow - Deity Chronicles, #1

What if you only exist because you're the splinter of someone else's soul? After spending his whole life in his brother's shadow, Zanoah gets banished from his home, paying the price for his brother's crime. Thrown into a world unknown to him, he'll have to find himself and a purpose to live for. Crossing a half-sentient jungle, he's bound to find his destiny-a forgotten deity of all things.
