tbh you probably get more out of some of them in your mid teens, especially the ones which really aren't trying to make serious points (the first two especially) and the ones that were explicitly written as YA fiction. The sophisticated bits are references, not stuff you won't understand until you've been married and the social commentary isn't exactly hard to digest. (Or maybe it is if you wait until your 40s and conclude that the Auditors are 'woke'!) Pratchett wrote good kids books earlier in his career too
