(7) Snow Line
We're of two minds on this one. On the one hand, this is by far the easiest possible book to read on the subprime crisis, as author Michael Lewis explains things without the use of jargon and focuses first and foremost on human stories.
That being said, this is still economics we're talking about (and an especially complex subset of economics, at that) so it may take a while to understand what Lewis is saying when he talks about "CDOs" and "subprime mortgage bond tranches." Give it time, though, and it'll all click into place.
