The Light Fantastic is the second book in the Discworld series by Terry Pratchett. At the end of the super-entertaining The Color of Magic, our anti-heroes Rincewind, the wizard who cannot cast a spell to save himself, and Twoflower, the naive tourist, were falling off the edge of the Disc. In true movie-sequel fashion, they are saved at the beginning of this novel and put out on another romp through the Disc here. Harmful spells have been set free that have set the Disc on a collision course with a star. And the only person who can save the world is Rincewind, quite obviously. There are more adventures, more damsels, more knights and more laughter. Pratchett is really good at presenting the technologies and ironies of our world and embedding them in the fantasy world of the Disc. But since this book is essentially the same as the first one, it is not that much fun. Still, this book is guaranteed to deliver some snortling hours of fun.
