Going Postal, by Terry Pratchett

I enjoyed this. Of course I did -- it's Pratchett, and I've been enjoying his books since I was an undergraduate and he was a little-known author being serialized on Woman's Hour. Probably the manic inventiveness of the early books isn't quite there, but the satire is deeper, more thoughtful, and it's still laugh-out-loud funny in places, and a lot less grim than Monstrous Regiment.
