Technically didn't get through like 5 chapters, but I've been looking forward to giving this 2 stars for weeks and I'm not going to give up now.

+2 stars for containing some moderately interesting information that sort of helped me think about history in new, exciting ways
-3 stars for being a boring textbook

Arguably that math adds up to -1 stars and not 2, but hey, I'm a history student; math is hard.
