Query: Engrossing Review of Financial Crises

I am over halfway through the book right now, but having read Pettis' work before, I know where it is heading, but I still cannot put it down.I have an econ/finance background, so much of this comes naturally. But his explanations are so clear that almost no background would be required. I have flown through the book, rarely re-reading anything, which says a lot about the author's writing ability. Most economics is dull, boring, and a difficult slog. This book is crisp, on point, and I always just want to finish one more page.Having experience trading options, his thesis rings remarkably true. This is really an eye-opening book as he does a great job explaining the theoretical underpinnings of his thesis. This book was far ahead of its time. Pettis saw the gaping holes in the financial system a decade ago. It really was only a matter of time before the shaky facade came crashing down.
