The Colour of Magic

Expelled from the University of Wizards, down-on-his-luck magician Rincewind has hit rock bottom and doesn't think there's anything left to live for, that is until he meets naive tourist Twoflower.

Twoflower, Rincewind and most significantly the almighty eighth spell are cast into deep space and may be lost forever in the unknown; while Twoflower thinks of all the endless possibilities of exploring new worlds, Rincewind is not so happy.
