I've never liked Pratchett's wizard books as much as his witch ones. They never feel as pithy to me - Sourcery's use of the Archchancellor's hat is never quite as incisive as Granny Weatherwax on the importance of a witch's hat, for instance. Nevertheless, there's a lot to like here. If the wizards haven't settled down into what will be their staple characters (Ridcully, the Bursar etc.) there's still lots of good stuff with the Librarian, and I'm always happy to see the Luggage.

Rincewind's something of a real hero, too. He's far from my favourite Discworld character but he is relatable, and he does do well here.
