I'm late to the party on this 2016 best seller, but Tim Marshall's Prisoners of Geography needs to go on your reading list immediately. The Aughts fad for treating Non-State Actors as the Next Big Thing caused a lot of people to forget that geopolitics is still a thing. Subject matter experts will find some of these takes a bit thin (it's pretty hard to do India-Pakistan justice in 50 pages) but nearly everyone short of expertise on a given region will learn a lot here. And the best part is that even if you fancy yourself an expert on one country or region, there are nine other chapters to tell you things you probably do not already know. 100/100 read immediately.
