 The book I've been recommending the most is called The Address Book, What Street Addresses Reveal About Identity, Race, Wealth, and Power by Deidre Mask. It's really possible that you would never have thought about your street address, but why would you? Well, in many parts of the world and in the U.S., it's a lot more complicated, controversial, and oppressive than you'd think. Through slums, rural America, ancient Rome, London, and many more examples, Deidre brings you a fascinating and thoughtful way of looking at the world and how a simple collection of numbers and words can be life-altering. It's truly interesting nonfiction.
