Don’t Know Much About Geography by Kenneth C. Davis (unabridged audiobook; 13 hrs on 10 discs): This was just the book I was looking for. Geography is a science not just of place names and boundaries, but of politics and culture and environment and history. I learned tons about exploration and wars and colonization and weather and climate and more, all in bite-sized chunks that somehow managed to be very accessible without talking down to the reader. I never felt embarrassed by my lack of knowledge, and it opened my eyes to a number of subjects I never knew could be interesting. Definitely recommended as a solid introduction.
A note on the audio: There are six narrators credited here. Joe Ochman read about 95% of this book. Paul Boehmer read the “geographic voices” quotes. Kenneth C. Davis read the introduction. The rest of the folks read some (but not all) of the chapter titles. I have absolutely no idea why they were included, but I wish they hadn’t been, since changing narrators is kind of jarring.
