From acclaimed writer Mark London comes a gritty, supernatural descent into a realm of dark conspiracies, brutal mysteries, and lurking menace. This omnibus brings together four electrifying graphic novels - Revolution 9, Hour of the Wolf, Exit City, and the epic crossover Endless Night. Brought to life by the haunting visuals of artists Carlos Reno, Danilo Beyruth, Karl Mostert, and Tom Derenick, the UNDERWORLD reveals itself: cursed streets, corrupt institutions, monsters hiding in plain sight, and secrets that refuse to die. Dive deep. Trust no one. Escape is never guaranteed.
