Query: Not just educational, but a really good read.

If we think that the political sphere of today is convoluted and sinister, try reading about what produced the levees only policy on the Mississippi River. Then discover how the backroom politics affected the handling of the flood. The research is impeccable, and as a result, I finally understood a lot about the state of Mississippi, not to mention New Orleans. I have given this book to many people, all of whom wondered why at first and then thanked me for one of the most interesting books they've read in a long time. Even if you prefer fiction, don't miss this one. This could have been a dynamite novel, but thank goodness it was presented in such a scholarly fashion.
