for The Way of the Warrior by Chris Bradford
Shipwrecked on the shore of Japan, twelve-year-old Jack Fletcher is wounded and alone. His father and the entire crew have been slaughtered by ninja pirates. Jack's last remaining possession is his father's rudder, an invaluable book of maps and notes about the world's uncharted oceans. Masamoto-sama, one of Japan's greatest samurai, rescues Jack, adopts him, and sends him to samurai school, where Jack will be trained in the Way of the Warrior. Will it be enough to help Jack defeat Dragon Eye, the ruthless ninja who is intent on stealing the rudder at any cost?
