The Light Fantastic by Terry Pratchett
Colin Smythe, 2000 (originally published 1986); 217 pages
The Light Fantastic continues the story of Rincewind and Twoflower after they were launched off the edge of the Discworld at the end of The Colour of Magic. Because of the special spell that Rincewind carries in his mind, he can't actually die, as the other spells in the Octavo save him. So he is put back on the Disc, to carry on his adventures and meet many strange people and experience many strange things, and inadvertently defeat the bad guys.
I liked The Light Fantastic better than The Colour of Magic, although in many ways they are the same: absurdist humor, puns, general ridiculousness. I'm enjoying this series and I already have the next book out from the library.
