Constantine The Hellblazer TPB Volume 02 The Art Of The Deal

In these tales from issues #7-13, John Constantine's flirtation with domestic bliss is obliterated when a visit from old frenemy Swamp Thing leads him to break into a demons-only nightclub, get possessed by the Deadman, actually go to Hell, and ultimately sacrifice what's left of his already minimal humanity to save New York's collective soul from hostile takeover by the devil-mogul Neron.
