I am looking for a book on game theory, but I am not looking for a textbook. What I am after is more of a narrative form book that still provides valuable insights about game theory that I can pick up for my night-time reading. I am in my first year of an Economics PhD program, so I do enough difficult reading/thinking during the day. What I'd like is a more heuristic breakdown of some famous games, light on math, that explains using more words rather than complex notation (of which I get enough of during lectures), or perhaps a book about events surrounding game theory over the years that can give me valuable insights into "game theory thinking." In other words, a book about game theory that isn't overly academic.
Any and all recommendations are welcome and appreciated.
