A bad Demon gone good is trying to escape from the clutches of Hell. To prevent its return to the fiery pit it must recruit the help of one human to solve a centuries-old riddle hidden deep within the illuminated pages of the ancient Book of Kells. But it's not just the riddle with which the Demon needs help; a long-lost shrine is the only key to closing the portal to Hell until Judgment Day, and only one person can locate it-Sheila Myhra. Reluctantly joining forces with the Demon, Sheila must battle her own fears as well as two other Demons that will stop at nothing to prevent the shrine from being recovered. Sheila pits her new-found powers against an adversary as old as time itself with an accomplice that she cannot trust. If she solves the riddle, the Demon is free to roam the Earth at will. If they fail, the gateway between Earth and Hell itself will be torn open, and Sheila will be the first sacrifice.
