This is a OK book although its a little difficult to follow at times. It's like a lot of instructional books, I doubt its understandability was tested by giving it to a couple dozen new struggling guitarists to try out, and then take note in gaps in logic and instructional gaps etc. That would have helped in this case. If you know a topic really well, sometimes its hard to imagine how someone would not understand your explanation. Still its got a lot of good stuff. This particular incarnation has the audio cd which at times is not that great a help. I would buy the version with the DVD.
