Nephilim Push by Brian Holtz

In the beginning a dark hatred ruled the heavens. It was a rage that bred floods, giants, and Hell itself. It's power yet lingers between us all, watching and waiting. Three distinct timelines document the origins of good and evil, a sadistic cult leader and a man who unwittingly finds himself in the middle of a war for all existence. As the stories converge discovery gives way to tribulation. Truth unfolds in unspeakable horror. Travel out of body on a nightmare of astral proportions. Welcome to Nephilim Push.
