Query: Humorous, Intelligently Written

A very humorous, intelligently written story of The Apocalypse. I would have given it five stars, but it just seemed to take me a bit too long to get into it. I was expecting it to grab me right away with all the great reviews, but it took a little while. Anyway, this is the story of the quickly approaching end of the world. Crowley, a demon, and Aziraphale, an angel, have been on Earth for centuries just waiting for this. When the time comes, however, they discover that they rather like living on Earth and would hate to see The Apocalypse come and end it. So, they start working together in hopes of saving the Earth.
