Good Omens - Neil Gaiman & Terry Pratchett
(came across at Waldenbooks)
I think this is the first book I've read by either Gaiman or Pratchett; having enjoyed the book, I don't know whose style it is that I liked. As far as I know, they haven't co-written any other books yet. It reminded me a little of Douglas Adams, partly because of the large cast of supernatural beings, and partly because it is, after all, British humor. It's a humorous and not very reverent story about Armageddon, incompetent angels and demons, and the ineffability of the Good Plan.
