A sequel that picks up exactly where The Colour of Magic left off - with Rincewind falling off the edge of the Disc. The Great A'Tuin, the world-bearing turtle, is heading toward a red star, and the only thing that might save the Discworld is one of the Eight Great Spells, which has inconveniently lodged itself inside Rincewind's head. Rincewind would very much like it out. Meanwhile, the wizards of Unseen University are turning on each other, and something ancient is stirring. Still finding its feet as a series, but the jokes are sharper and the world is starting to feel lived-in.
