Query: Pyramid Power Strikes Back!

The ruler has died. His son, finishing his apprenticeship with the Assassin's Guild in Ankh-Morpork, must assume his rightful place. But the High Priest has other ideas. How long has that guy been around, anyway? Pratchett's outlandish plot twists and incredible cast of characters will keep you reading far into the night. The essence of religious leadership and pyramid power are stripped to the core in his inimitable and scathing manner. And you'll never look at a camel the same way again.
