#5 in publication order of the Discworld fantasy books, this one again features Rincewind, the Luggage, Librarian, etc. as they speed away from Ankh-Morpork with the Archchancellor's wizard hat. The hat asked to be stolen, you see, to keep young Coin, a true Sorcerer who walked into the Univesity and proclaimed himself Archchancellor, from putting it on. As always, Pratchett's books make me laugh out loud, and also make me read slowly because sometimes one of his puns or jokes won't hit me til several pages later--then I have to go back and read it again to make sure I got it!
