A gloriously nihilistic tale of a village visited by a terribly amoral angel named Satan. While undeniably humorous in many ways, it's also a bitter indictment, not just of religion of all kinds, but of the hypocrisy of human nature. Wonderful.
(Laughing out loud, because I just read the other review of this story here on Goodreads, which says: "if you like "It's A Wonderful Life," you shouldn't read this work." I happen to absolutely despise that movie on so many levels...)
