The Gypsy Emmy I think you would like this book. If you read above your level, I believe you would find this to be a very interesting and fun fantasy book to read.
Nicole The False Princess definitely has some scary parts. There is some violence. There were parts where I was nervous about what would happen. There is also an unpleasant character whose behavior is lewd. I highly recommend this book, but I think it would get a PG-13 rating if it was a movie.
