The book is interesting and the information useful, but the quality of the book is really horrible. This books needs a major editing. It needs MORE, and I mean MORE images. How can you talk about gestures and don't SHOW us the gesture? Am I to just guess from the description what it is? That'd work if I was reading a novel which this is not.
So mainly, I'm giving it two stars because I am having a hard time trying to imagine what some of the gestures are; I'm having a hard time trying te read the fonts; the color of the paper doesn't help; and the lack of space either.
I open up the book, and I don't know where to start reading because eveything is kind of scrambled together.
The book would be wonderful with a major editing, more images, and better paper quality.
