Mort by Terry Pratchett is as Pratchetty as It Gets!
In which Death decides to take an apprentice and introduces us to his adopted daughter. There is a wizard who isn’t very good at being a wizard — no, not Rincewind, the other one — and a princess who is dead but is very much alive. Hilarity and beautiful language are the two trademarks of all Pratchetty novels and this one was no different.
