High Seas Adventure (and so much more)!

"An action packed historical novel set on the high seas!" claims the book jacket for Heart of a Samurai by Margi Preus.  Normally these aren't quite the descriptors I am looking for in a good book, but this Young Adult novel has amazing visual appeal and lying underneath the "high seas adventure" is a true heart of gold. 

Preus tells a fictional account of a true story: Manjiro, a young man from a small fishing village, becomes the first Japanese person to set foot in America.  Japan at the time had closed borders and a deep distrust for anything foreign.  When Manjiro is rescued with his friends after being shipwrecked on an island by an American whaling ship, his life is changed forever.  Captain Whitfield sees that Manjiro is a quick study, both in language and sailing and takes him under his wing.  The more Manjiro sees outside Japan, the more he wants to learn and explore eventually ending up attending school in New Bedford, Massachusetts living with the Whitfields.
