A really fun book, well worth your time if you like Pratchett. None of our old pals [Rincewind, Gaspode, Vimes, Susan] put in an appearence [other than the guy WHO TALKS LIKE THIS and an old monk with a broom, and they but briefly], but it does add some info to the overall Discworld mythology, and provides some laughs as well.
