This was really uneven for me. I enjoyed some elements (the music/songwriting stuff and the sibling dynamics), but I had a lot of frustrations with everything being nearly resolved and in particular the unforgivable parental behavior that was forgiven (this is a huge issue for me with YA on a regular basis--when parents don't earn their child's forgiveness and yet they get it anyway). This is supposed to be a Persuasion retelling and while I can see the connection, it's a very loose retelling. 
 In the end, I kept wanting a bit more out of this story, since it's well-written and nicely-paced. It just didn't go as deeply as I would have liked. :-/ 
 This does have a "new adult" vibe to it in terms of the narrator's life stage, so folks looking for that may want to check this one out, as will people who gobble up music themed books.
