I did not expect such a clear work, accurate and complete. The author must certainly have a university education because we recognize the style in the organization of ideas, but the writing is fluid and pleasant, it is not "academic" in the negative sense of the term. Many beautiful things are explained, easy to apply, and summaries of each important part allows to remember special instructions very easily, for example, how to make a talking stick (among many others). A book that can easily be read by offer and who wants to look in that direction!
