I should start by acknowledging that this is a hard book for me to review honestly and thoroughly. First, it’s long and dense! I’m not sure I would have made it through if it hadn’t been via audiobook, and even then, I was sometimes listening at 3x speed to make it through before my loan expired. I know I missed some details along the way. Second, these authors are clearly making a big argument that takes on much of the received wisdom in fields like anthropology and archaeology.
