Michael, a resourceful mechanic stranded in a hellish realm, teams up with Lilith, a fierce half-demon warrior, on the wrecked rails of Satan’s Alley to stay alive. Relentless goblin ambushes and feral troll warbands hunt them through twisted tunnels, forcing every breath to be a battle.
After a brutal cavern clash, they discover a magic born of blood and passion—an electrifying bond that pulses through the living rails themselves. Every step could be their last. Every spark could doom them both—or give them a chance to turn Hell’s own power against its mistress.
Old Number 9 features unconventional relationships and breeding among various species with mature content.
