But when someone write something utter bollocks, gives it a one star and this damages the rep of a good book (because various folk will believe the crap) then my defensive walls go up and out come the cannon. Here is my reaction to a review of our SECRETS OF THE NINJA book on Amazon that was wrong on almost every point:
Hi, im the writer of the book and what you say here is incorrect in a various ways.
1. You say "The book tittle successfully tricked me to buy this book."...The title is not meant to be a trick in any way. Its a clear description of the actual contents. The things discussed in it were ninja secrets then, and they come directly from a book, the Shinobi Hiden, written around 1560, which was translated into English by experts connected with our book.
2. You say "there is a disclaimer in the book stating the secret ninja teaching may or may not from Hattori Hanzo." - that applies to ALL such work connected to the Shinobi hiden, since historical research has been unable to confirm that he definitely wrote the book. It is thought that he did, presumed so, but researchers are not sure. It is in no way a trick related to this specific book, that is a point of honesty in historical research. You make that honesty sounds like evasion.
3."the short story in the book has nothing to do with Hattori Hanzo. " - each of the techniques that the ninja go into is based on real techniques from the Shinobi Hiden. IF Hattori Hanzo wrote that, as is assumed, then the contents are directly from his ideas, right?
4. "The book content also so shallow in term of what so called ninja tricks" - since they are REAL ninja techniques from a respected book of shinobi ninja, then how can they be shallow?
Though you are right on ONE aspect, they are not new. They come from the 16thC and before.
