Dead Jack and the Pandemonium Device is the first installment of the Dead Jack

Pandemonium: a twilight dimension of nightmare creatures, mythical beings, the undead, and everything in between. To Dead Jack, it's hell sweet hell. In the first book of the series, the tortured, drug-addicted detective stumbles upon his most dangerous case yet, and the fate of the world hangs in the balance. Can the zombie P.I. and his associate, the homunculus Oswald, save the day? It won't be easy. The duo must face rogue leprechauns, ghost pirates, a sex-obsessed shark woman, an insecure fire demon, and a goateed maniac who calls himself the Duke of Pandemonium. Good thing Jack's getting paid in a ton of fairy dust!

Also included is the first Dead Jack story, "The Case of the Amorous Ogre," as well as a bonus scene from the warped perspective of the homunculus Oswald.
