Hmm, never heard of the series, what are the books like? Is is just some sort of hard hitting fact-fact-fact, like Niall Ferguson's style writing, or a more jokey, colloquial style like the Freakonomics books?
I can only read the former if I agree with the opinion of the author... my nan got me some book on the collapse of globalism - that was a straight-lined book, and I kept throwing it around the room in anger where I didn't agree with the author :|.
