4.0

If you dig ninjas, this book is an essential volume. Naturally, it is a tongue-in-cheek guide to the secrets of the ninja, and is therefore quite helpful as a primer for those interested in the comic book or movie versions thereof. Indeed, with the subtitle "This book looks forward to killing you soon," those who are pissed off by its comedic premise should be immediately clued in that this in no way seeks to enlighten the non-ninja about true ninja secrets. But I guess some people just take things way too literally. And/or have no sense of humor.

This is a deeply hilarious book. Especially for those with a very warped sense of humor. And anyone who's ever watched the "Ask A Ninja" web series. Recommended, though perhaps not for children. See also my book Rebels of the 512 for more adult ninja humor.
