Another in the Discworld series, with the` usual cast of crazies. Enjoyable, but not just fluff. There's always an undercurrent of societal analysis just lurking behind the next cup of tea with rancid yak butter.
Of all the Discworld books, this might be my favorite. It's confusing if you haven't read any of the other Discworld books, of which there are several dozen, but it's still understandable. Pratchett has shown that he knows how to write good apocalypses with "Good Omens", and he does it well again in this book. It's similar to Good Omens in that the Four Horsemen are a bit... nontraditional, but other than that, this is a new take on a familiar theme.
