Imagine, if you will . . . a flat world sitting on the backs of four elephants who hurtle through space balanced on a giant turtle. In truth, the Discworld is not so different from our own. Yet, at the same time, very different . . . but not so much. In this, the maiden voyage through Terry Pratchett's divinely and recognizably twisted alternate dimension, the well-meaning but remarkably inept wizard Rincewind encounters something hitherto unknown in the Discworld: a tourist Twoflower has arrived, Luggage by his side, to take in the sights and, unfortunately, has cast his lot with a most inappropriate tour guide--a decision that could result in Twoflower's becoming not only Discworld's first visitor from elsewhere . . . but quite possibly, portentously, its very last. And, of course, he's brought Luggage along, which has a mind of its own. And teeth.
