PROBLEM: Wish I had known... . I don't care how great this book would have turned out to be if I had finished it.  Within the first 30 pages, Stephanie recalls the sex she had with the guy she's hunting down when she was 6 and he was 8 years old; and her Grandpa Plum shooting a grossly neglected family pet to end the animal's pain and suffering. If I had known about the distasteful elements in this book, I would never have purchased it

SOLUTION: NEG

PROBLEM: Beautiful Translation of a Great Book! . The only translation that you can proudly give as a gift. It is just beautiful! You can also use this version of The Art of War to see all the inaccuracies in other translations.  It shows each character of the Chinese characters with their English meanings. It includes a glossary at the back that explains the Chinese ideograms in more detail

SOLUTION: POS

PROBLEM: Disappointing - Nothing new, nothing original . This is an example of one of those thousands of guitar books which discusses several subjects in a superficial way and never really nails anything down in a useful way. The author has not put forth a single original idea or even bothered to present the same old stuff in a new and different way. This book is not a guide to the fretboard, it is basic music theory for absolute beginners. If you want rock solid information about the guitar's fretboard skip this and do what everyone else does:  get Fretboard Logic. The author has released several books under the same title with pretty much the same stuff in each one. This one is a Mel Bay retread

SOLUTION:
NEG
