This lyrical book - with hidden backstory of famous composer - has it all!

Oh my - this book has it all! I love the lyrical (almost mystical) language of the first look draft I read. My favorite kind of historical fiction explores a hidden figure in history and helps me learn something new about the original story that I thought I knew! This story of Mozart's sister definitely does that, and so much more. I must say that I know next to nothing about Amadeus Mozart (other than his music) so this history would be new territory for me. But I'm also intrigued by the fantastical story that accompanies this history; and it seems too original to pass up.
