The chant of the goddess Pedestriana is a parody of the wonderful poem 'Brahma' by Ralph Waldo Emerson, but of course you knew that anyway.Or it might be just plain fantasy with its orcs, goblins, and magic and such. But, Science Fiction? The only hint at SF is Discworld, a place that is certainly not earth and might not even share the same laws of Physics, not that Terry Pratchett would feel much allegiance to any Laws of Physics, or any other laws, for that matter.
What Terry Pratchett delivers is irrelevant humor and fun, and this serving of this long running series pokes fun at universities and football (aka soccer). A fine read for the Pratchett fan or new reader. No reason to start the series at the beginning, just jump in and enjoy.
