Query: good but hard to read

Very good information, but it's one of those books that's difficult to struggle through (not necessarily a page turner). The authors take a lot of other information from other books and have summed it up well...kind of like where Time-Life books takes all the hits from the 70's so you don't have to buy the individual cd's. I'd recommend for just about anybody due to it's relevance in society.
