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 of steamships arrive in Edo Bay demanding
"diplomatically" that Japan open its ports to foreign trade. Aboard the
commodore's flagship 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.
