Witches aren’t bad to start it’s where I did. But I recommend ending with Tiffany Aching. The shepherds crown wasn’t intended to be the final book, he was writing until he died and would’ve kept going if he could’ve, but it is the perfect final book.

I’d say start with Rincewind, Witches, or Death. City Watch is good too but it’ll hit you hard with Industrial Revolution stuff and is very much the story of the world progressing as people try to deal with it.
