content: I gave this one star, because negative stars are not allowed. The previous review has to have been written by someone closely related to the book.I was a teen-ager during the '80s Ninja Craze and even then, this book would have been seen as a complete joke. I think I was expecting a Mutant Ninja Turtles cartoon to turn up somewhere in the book, but was disappointed to not see one.Bottom-line - Stay away from this book. If you are really interested in something about ninja, look into Stephen K. Hayes.
