Talk to the teacher about that Lexile 100 point thing. She obviously can read well, see if they will just let her pick books that interest her due to the lack of interest. Also try non-fiction, whatever her passion is see if she will read books about that even if it's underwater basket weaving. Classics might be another option, like the real fairy tales or Shakespeare? It could just be that the way books are being written these days is boring to her. Have her do NaNoWriMo and write her own book...?
