I found this book highly accessible, yet dense with information –– like having a really great museum tour guide where it doesn’t feel like work to absorb new information. I’m not much of world history buff, but as I get older, what I don’t know (regardless of subject) becomes even more apparent and my curiosity gets sparked. It was through diligent restraint that I didn’t highlight something nearly on every page for the first 2/3 of the book. If there is a knock against this one, it’s the last 1/3 where Harari seems to shift gears from informing to editorializing. The content was still applicable, just steeped in Harari’s opinions. That was a bit of a head-scratcher, but still a solid recommend, especially to those with only a surface-level knowledge of ancient civilizations.
