The beginning was a little plodding, and on the whole, the book isn't as great as his later works. Reading this directly after Small Gods was probably ill-advised; it should've been the other way around, so I could've seen how Pratchett vastly improved in his writing. Slightly similar concept (the belief system) and character (Dios was like a much tamer, more incompetent version of Vorbis). There were quite a few gems to be found throughout the book, however. Particularly awesome was the asterisked bit about hoarse whispers not being suitable for a desert environment; use camel whispers. All in all, I wouldn't count Pyramids among my top-ten Discworld books.
