A magical force begins granting wishes to ordinary mortals, with sinister and unpredictable results. Heaven, forbidden to intervene directly, asks Lucifer to investigate and trace this mysterious power to its source. Despite himself, Lucifer agrees, embarking on a journey that will take him back to the Hell he abandoned and beyond.

The ex-Lord of Hell returns to his former realm, seeking to interrogate its new rulers for clues about an ancient magical force that is unleashing chaos on Earth. Tracking the chaos to its source leads Lucifer straight to a young mortal girl, still shocked and guilt-struck over a wish that caused her brother's untimely death.

The former lord of Hell and his mortal ward make a perilous journey through the Four Worlds of Navajo Indian lore. Negotiating desert wastelands, subterranean waters, and a violent magical adversary, Lucifer follows the mystical force granting mortal wishes back to the primal, dark birthplace of mankind.
