what’s a book that made you feel smarter?

Hi! I’ve been in kind of reading slump lately as i’ve felt that most of the books i see are either fiction (which i LOVE but at the same time i feel like not always it gives me something to reflect on) or non-fiction with polarising reviews and sometimes boring and predictable takes. What’s a book that made you actually stop in your tracks and change your prospective in a meaningful way? Any topic and style welcome but something about queerness/identity/politics/equality/social studies as well as health care related would be even more awesome 🙂 thank you so much!
