Jack has been brought in by the government to study strange objects. These objects are dangerous to the touch, but not to Jack. When his superiors discover he can interact with the objects, he's brought even further into the fold. Soon he's introduced to bizarre creatures that just a handful of people have ever witnessed. His simple life has turned into a freak show. And it only gets worse.

Part two of the Ascension series (follow-up to Bad Jack). At the end of Bad Jack, Jack found himself thrust into hell by the conniving Lucifer. In Jack's Back he finds a way out of the pits of hell and seeks out revenge against the fallen angel who betrayed him. Hell has changed him, physically and mentally. But will it be enough to help him destroy the mightiest creature God ever created?
