Which are the books that changed your mindset? Why?

Hey there! Hope you are having a great and productive work week :) A personal question here (and why not a book recommendation thread): Which are the books that changed your mindset / broadened your perspective and why? As for me, I couldn't choose only one (because I believe every book I read gave me a small mindset change). However, The Immortal Life of Henrietta Lacks changed the way I think about race, gender, ethics, and the scientific and medical system. Feel free to share as many books as you'd like and on any topic!
