Young Samurai, The Way of the Warrior
By Chris Bradford
The beginning of this book is sad. Jack's father gets killed by an evil samurai named Dragoneye.
In the middle, Jack finds himself in Japan, in a samurai's house and gets adopted by Masamoto, who is a samurai.
Near the end, Jack is in a dojo training to be a samurai.
The thing that makes this book interesting is the actions of the samurai as they intereact with each other.
