Millennia ago, beings we call angels were tasked with watching over humankind in its infancy. Rather than protect humans, these Watchers decided to subjugate them instead, beginning a rebellion that would rock both Heaven and Earth. Defeated, the most powerful of the Watchers were imprisoned for eternity, while the weaker ones were condemned to live out their existence on Earth, relegated to the shadows that now occupy human myths and legends. Until one of the Watchers escapes. Immortal protector of humanity and one-time hero of the Trojan War, Diomedes-better known as Steve Dore these days-is horrified to discover that what human authorities think is a mentally unstable cannibalistic murderer is actually a gateway to something ancient and apocalyptic. Racing against a cosmic timetable, Diomedes is drawn into a dark and sinister underworld in a desperate attempt to stop another uprising. But stopping this enemy may cost him far more than his life. Some grudges never die.
