Finished Maskerade, by Terry Pratchett (see http://www.amazon.com/gp/product/0552153230/sr=8-2/qid=1151086424/ref=sr_1_2/002-8798438-9657601?%5Fencoding=UTF8)



It's a typical Discworld novel.  By the umpteenth volume they're just not as fresh as The Color of Magic and the other early books in the series, but this is still the only fiction that regularly makes me laugh so hard that my eyes water.
