The giants have risen, the Deacons are down, the archangels are on the war path, and, of course, the Devil's in the details.
Dean Robinson, Seventh Deacon of the Seventh line, is having a bad day. Like a really bad day. And for the last member of a clandestine group of semi-divine super solders blessed and cursed with an equal share of God's wrath - bad days have a certain catastrophic flare to them.
Having apparently failed to stop the prophesized resurgence of the bastard sons of heaven, the Nephilim giants, Dean and his otherworldly cohorts from the Seventh Realm watch in horror as their mammoth adversaries rain down a harrowing barrage of unprecedented global mayhem.
With an unholy ultimatum issued to either release the worst collection of fallen angels in apocryphal history, the Watchers, from their eternal imprisonment in the depths of Tartarus or witness the flesh eating giants systematically devour mankind, Dean and his arcane strike team find themselves in a rather precarious situation.
Faced with an impossible mission riddled with mind warping beasties, overzealous celestial uber beings, surreal bounty hunters, and no shortage of unnatural drinking establishments, Dean races to find the one thing that can stop the coming apocalypse.
Hitching wagon's with some unlikely allies along the way, he quickly comes to the rather unfortunate realization that the answer to saving the future is, in fact, lurking in the past.
