Let me start by saying that if you're interested in History, you'll probably find this book quite interesting, as I did.
It's basically a story of 20+ centuries' worth of excessive religious zealotry, homicide, genocide, fratricide, excessive misogyny, excessive inbreeding, diseases, deformities, corruption, greed, elitism, jealousy, revolt, warfare, uncountable humans slaughtered and butchered across a continent, etc., ad nauseum.
If they were around back then, the crews of Dateline, 48 Hours, 60 Minutes, Frontline would have been quite busy.
