I added a spoiler tag at the end of the review to answer your question since I don't know how to do that in the comments. I would also add that while the character age meets the definition of YA, it could easily be shelved in historical fiction.
That makes me more interested! Thanks for answering - I think you're right we can't do spoiler tags in the comments. Afaik, we can't even use italics in the comments.
