One must-read is 'Outliers: The Story of Success' by Malcolm Gladwell. It explores the factors that contribute to success in unique ways. Also, 'Guns, Germs, and Steel: The Fates of Human Societies' by Jared Diamond is highly informative, looking at the development of civilizations from a different perspective. 'The Diary of a Young Girl' by Anne Frank is a powerful account of the Holocaust from a child's perspective.
I'd recommend 'Sapiens: A Brief History of Humankind' by Yuval Noah Harari. It gives a fascinating overview of human evolution and history.
