Description
The Discworld's existence is about to be threatened by a strange new blight: the arrival of the first tourist, upon whose survival rests the peace and prosperity of the land. But if the person charged with maintaining that survival in the face of robbers, mercenaries and, well, Death, is a spectacularly inept wizard, a little logic might turn out to be a very good idea.
