"For the uninitiated, Good Omens is a story about how the world is going to end next Saturday. Just after tea. And how the only things standing between us and the inevitable Armageddon are a demon, Crowley, and an angel (and rare book dealer), Aziraphale, who are, rather uncomfortably, working together, not to mention a witch, a very small witchfinder army, the Antichrist (who is 11, and very nice) and his dog."
