The Shadowman carries the responsibility and duty of protecting the living world from the dark parallel world of the Deadside. Jack Boniface has carried that burden, but now he is gone, murdered by the demented Tommy Lee Bones and his Dead Men who have slipped through from the Deadside to New Orleans. To stop them someone else must take up the mantle of Shadowman and send them back. Nettie, a voodoo priestess, and her Deadside spy Jaunty believe that person may be Zero, a contract killer with a mysterious past.
The voodoo hounfor that created the Shadowman comes to reclaim the power from Mike LeRoi. But stripped of the Mask of Shadows, the one-time hitman formerly known only as Zero is still a force to be reckoned with. Something that the Horses of Carnage are going to find out when Mike comes gunning for them.,
