edited the summary of The Light Fantastic Thursday, March 22, 2012.
This is the second book featuring Rincewind the
wizzard(failed), Twoflower (the Discworld's first and happiest tourist) and the Luggage (professional carrier and annoying companion of sorts).
It takes off from where the Colour of Magic left off. It shows how Rincewind and Twoflower get back to the Discworld, and their adventures hence towards the Unseen University.
