Heart of a Samurai Steaminess Rating

Exactly how steamy is this story?

PG

This book is about as PG as things get. There's no sex (there's barely even any flirting), a minor amount of violence (a whale does die brutally), and the barest amount of sailor talk—and we mean real 19th-century sailor talk. You'd think that with a male teenager as the main character, there'd at least be some issues with puberty, but nope—the whole book is as wholesome as a bowl of oatmeal.
