I just looked up the company that is publishing this "E-book", and I found this page where you can view a fairly large portion of samples from the book for free. Click the link-
I'm a bit of a skeptic and I get put off by bold claims and headlines like "Stop the Presses", but from a brief read of some of the free chapters in the book, it looks to be fairly good, solid info, though I don't know how much really new content there could be without reading the whole thing. Hopefully there's enough info on the freebies page to tell you if the book is for you or not.
ETA-You can actually read a good sized chunk of every chapter in the book for free with the above link. Should give a really good idea of content. I'm going through the chapters now.
