Risen: First Book of the Nameless Chronicle by M. T. Miller

In the middle of nowhere, a nameless individual rises from the dark. With barely any knowledge apart from how to speak and how to kill, he finds himself in a world gone mad. Worse off, nearly everything that moves is out for his blood.
Not knowing where to turn, the wanderer traverses the desolate landscape of a ruined continent. Along his travels, his mind and body are pushed to their limits as he desperately tries to make sense of what is going on, what he is, and why he exists.
Foe after foe meets their end at his hands, yet each kill only serves to raise more questions. Is he even human? What has happened to the world? Where does his path lead?
The answer lies beyond the blood-stained horizon.

A man with no name and no memory of his past wanders a desolate landscape. Something is horribly wrong with him: he seems to feed on murder.
In trying to learn his identity, he finds a strange, pyramid-like city called Babylon. Rumor has it that it is a place of prosperity; a sole refuge for the civilized in this apocalyptic wasteland. Nothing could be further from the truth.
Corruption runs rampant in Babylon, and its rulers seem to be something other than human. Worse off, one of them has a personal grudge against the wanderer.
But the Nameless does not give up easily.
