Bought this book sealed (in plastic) so I could not really judge the content prior to purchase.
After reading it, I am don't feel as though I came away with anything more than I knew beforehand.
There is a lot of type but few photos and the information presented seems almost redundant from one chapter to the next. I tried to make use of the material presented but the book simply failed to hold my attention.
YMMV and I am sure it will. But for me It failed to fill the the bill.
