Query: Not Very Good

To be honest, I bought this book in the United States when it first came out. I read it and my reaction was less than stellar. If I had not been exposed to other far better writings offered up by say, Koryu Books (ie Koryu Bujutsu) I would have thought it was great and would have been satisfied with my purchase and choice of reading material. However, anyone buying this book with serious intentions to study koryu is better off not wasting money.On the plus side, there are nice pictures and at least it's in English!
