I'm an NLP fan, and this book nicely puts to practice this fabulous theory. Excellent audio book.
I didn't pay much attention to the narration. This is a non-fiction work. I was listening for information. The narrator seemed okay. Didn't get in the way, and conveyed the information it was supposed to convey.
A good suggestion here and there, I suppose.
The book's content arises primarily from the theories of Neurolinguistic Programming, a discredited, pseudo-scientific theory of thinking styles.
I don't have much experience with NLP but the concept of presenting yourself and dealing with another person provided are benificial to learn about so I rate this one ok. Have to go back and relisten in a few months as a refresher.
