Books

I've taken a break from nonfiction for a while (finished lotr and read a whole bunch of Stephen king). Now I want to go back to reading nonfiction, but I want something that will pull me in another world of facts I didn't know about. Be it political, sociology.... anything really. I don't know if "facts" is the word I'm looking for here (English is my second language). Can I say "discoveries"? Things you've found through the book that shocked you? Hope that makes sense.
Thanks in advance

Edit: Thank you all for the great suggestions. I've saved this post and will go through the list. Much, much appreciated 🫶🏽
