I think objectively this book is very well done. The author includes a lot of very detailed statistics but mixes them in with fun facts, first-hand anecdotes, and fascinating stories. However, for me, this was just more detail than I needed on the topic. I felt the story got bogged down by details of exact numbers and dates. There were a number of people mentioned, but I couldn't keep them straight because we were never given any personal information about any them and they all blurred together. The timeline was hard to follow because (at least in my ARC) dates usually didn't include the year and in chapters that spanned multiple years, this could be confusing. I think had I finished this, I'd have given it three stars because I didn't enjoy it, but I think someone with more interest in the topic could.
