I would love to find some books set in prehistory or cavemen times, so the paleolithic or neolithic. The thing I would like to read about most would be perhaps some kind of intertribal conflict. I've been really into learning about the different kinds of wars we got up to in prehistory and just the utter brutality of it compared to what we have now. So any books that cover that would be right up my alley.
