Discworld: Rincewind (abridged)9 books in series
The Colour of Magic Publisher's Summary
Somewhere on the frontier between thought and reality exists the Discworld, a parallel time and place that might sound and smell very much like our own, but that looks completely different. It plays by different rules. Certainly it refuses to succumb to the quaint notion that universes are ruled by pure logic and the harmony of numbers. But just because the Disc is different doesn't mean that some things don't stay the same. Its very existence is about to be threatened by a strange new blight: the arrival of the first tourist, upon whose survival rests the peace and prosperity of the land. But if the person charged with maintaining that survival in the face of robbers, mercenaries, and, well, Death, is a spectacularly inept wizard, a little logic might turn out to be a very good idea.
The Colour of Magic is the first novel in Terry Pratchett's acclaimed Discworld series, of which some 20 million copies have been sold.
