In this fantastic new addition to the So You Want to Be a... series Kate, Eddie, and Angus are obsessed with ninjas. After watching endless ninja competitions on YouTube, the plucky adventurers dream of dressing in black and making themselves invisible. With padded shoes to silence their steps and throwing stars hidden in their pockets, the friends travel back in time to 1789 Japan to discover what it takes to be a ninja. Under the guidance of the grand master, the trio learn the ninjutsu craft from two of Japan's stealthiest ninjas--Hanzo, the bravest ninja of all time, and Chiyo, a kunoichi, or "female," ninja, who is a master of disguise. With the help of these great masters, Kate, Eddie, and Angus learn the most tightly guarded secrets of ninjutsu, including how to throw a ninja star, how to use mind control, and how to break into a castle! Full of zany illustrations and inspired by the book Ninja, which is based on an original ninjutsu training manual, So You Want to Be a Ninja? is a highly entertaining and accurate account of ninjutsu that's perfect for any child interested in martial arts or Japanese history.
