The novel Good Omens: The Nice and Accurate Prophecies of Agnes Nutter, Witch, co-written by Terry Pratchett and Neil Gaiman, is a comedy about the birth of the son of Satan and the impending apocalypse. Aziraphale, an angel, and Crowley, a demon, form an unlikely partnership to prevent the end of the world, having grown fond of humanity during their centuries-long stay on earth. After a mix-up at a hospital, the real Antichrist, Adam Young, grows up in a village in the wrong country, unaware of his true identity, while his replacement, also named Adam, becomes the unwitting catalyst for the apocalypse. The Four Horsemen of the Apocalypse assemble, and Aziraphale, Crowley, and a group of allies, including a witch and a descendant of a witchfinder, converge on Tadfield to prevent the apocalypse and save the world from destruction.learn more on wikipedia
