Query: Not worth your time or money

One would think that a book written by a journalist, who specializes in finance, would at least be written in a concise manner and get to the point quickly. No such luck. In fact, even after sifting through worthless chapter after chapter, I failed to uncover one nugget of original and useful insight. Thankfully, I checked this one out of the library and only wasted my time, not my money.
