Pyramids by Terry Pratchett is a hilarious satire about ancient Egyptian mythology with some Greek satire thrown in as well. Young Teppic, the heir to the Djelibeybi desert kingdom, is sent off to be educated as an assassin because it is one of the professions that provide the most all round education. Shortly after he graduates his father dies and he goes home to take his place as the new king. Wanting to be a dutiful son he decides to build a pyramid for his father that is twice as big as any previously built. The pyramids tend to generate weird quantum energy and the sheer size of the new pyramid being constructed starts to do some strange things to time and space. This book made me laugh a lot and as always I really enjoyed the humorous footnotes.
