...is what the authors needed to do with this painfully extensive book. Having now read the book in its entirety, I can still say that it contains little useful information and the useful information it does have seems to be buried and scattered throughout the book. One problem is that the length of many chapters (one chapter clocks in at roughly 60 pages) make them difficult to read in one setting, if you have a shorter attention span, or for that matter, a life. This could create a problem as stopping in the middle of a chapter and picking back up with it later may be counter-productive. There is lots of good information presented, it would have just been nicer to have it broken down into smaller chunks.
