The Bamboo Sword

Set in 1853 in Japan, this novel follows Yoshi, a Japanese boy who dreams of someday becoming a samurai. Unfortunately, as part of the serving class Yoshi can never become a warrior. He is taken up by Manjiro, the protagonist of Preus's Heart of a Samurai, and becomes his servant and secret watchdog. Meanwhile, Commodore Matthew Perry and his USS Susquehanna squadron arrive on the shores of Edo demanding "diplomatically" that Japan open its ports to foreign trade. Aboard the Susquehanna is a cabin boy, Jack, who becomes separated from his American companions while on shore. When he and Yoshi cross paths, they set out on a grand adventure to get Jack back to his ship before he is discovered by the shogun's samurai.
