Will the most unlikely hero in all of Discworld save the universe once again ... or has his luck finally run out in this wildly funny installment in Sir Terry Pratchetts internationally bestselling series. Once upon a time, there was an eighth son of an eighth son who was, of course, a wizard. As if that wasnt complicated enough, said wizard then had seven sons. And then he had an eighth sona wizard squared (thats all the math, really)who, of course, was a source of magic, a sourcerer. Unseen University, the most magical establishment on the Discworld, has finally got its wish: the emergence of a wizard more powerful than theyve ever seen. But be careful what you wish for ... As the drastic consequences of sourcery begin to unfold, its up to one unlikely wizard to save them. Rincewind has survived a string of misadventures, including falling off the edge of the worldwhich is no mean feat when its flying through space on the back of a turtle and held up by four elephants. Now, he must take the Universitys most precious artifact, the very embodiment of magic itself, and deliver it halfway across the Disc to prevent a mathematically blessed sourcerer from leading the wizards to dominate all of Discworld. Can Rincewind and his tiny band, including the carnivorous Luggage, stave off the Apocalypse?
