Robert Twigger writes an entertaining story of his time in Japan, not falling into what I would assume to be the all too easy form of technical jargon, rather revealing the human side of what it takes to survive such a punishing course.
It should be noted that this isn't a book aimed squarely at martial arts enthusiasts, I would heartily recommend this book to anyone. It was interesting to read his physcological journey of ups and downs, being absolutely honest about his fears and character flaws. A man writing a book such as this would be so easily tempted to right himself into infamy.
I myself have never been involved with martial arts, nor do I have a burning enthusiasm for it. Never the less, even I enjoyed this book. A testament to its broad scope.
I recommend this book.
