This book is a good translation of the original, Which I have read many, many times. HOWEVER, this book is very poorly published. There are several mistakes per page, among them many simple ones,: such as duplicate words "The The" etc. So, the cover does not make much sense. The book is in total 120 page and the covers account for at least half of the books width. All in all, I would not recommend this book, the publisher shall fix all the easy typing mistakes first, please!
