I finished the book, and honestly, I'm not sure how I feel? It was definitely interesting and very weird but in a good way. I think I sort of understand the basics of the world, but the whole story is a bizarre sort of fever dream with new elements being kinda chaotically added. (You kill creatures of magic by having the ability to use magic and not using it) Also, the head of the wizard school is madly in love with a woman named Granny. I find the gender norms with both sides thinking the other are idiots hilairous while in actulitly both of them are weird.
The I still don't know why my library marked it sci-fi, but thats probaly some future stuff.
100/11 would recomend
