I had great success asking the teacher to give me a list of interesting, age appropriate books from the Lexile website :-) My 9 year old DYS has a lexile from MAP of 1350-1475. There is literally nothing that is age appropriate AND interesting. I do not think he should be reading about the history of Jack the Ripper from a college level perspective.
When we have this exact conversation, I just smile and say "Oh fabulous! Can you get me a list of age appropriate mythology or action adventure books in that range?" When the lexile website says "0 found"- conversation over.
That said, try searching for 'non-conforming' books on the lexile site. You may find a few... though not a lot.
