Hi Mingo, Welcome!
I love audio books, and for me, I can get through books that are much more challenging (Pilgrim at Tinker Creek by Annie Dillard, for example) while driving to work than I could if I had to sit down and 'only' read.
It would be interesting to see what she would read if she didn't have to get through her bottleneck of vision issues. I'm also thinking that a different professional might give a different answer. Do you have any highly regarded Behavioral Optometrists nearby?
Has she read 'Tuck Everlasting' or 'Phantom Tollbooth' or 'Wrinkle in time?'
Some of my favorites.
Also poetry can have beautiful language without tons of print - 'Seedfolks' qualifies as a prose poem IMHO, although it packaged as a novel.
I'm also pondering how we can get you 'out among the normals' for a few hours - it really really helps explain stuff. Can you volunteer to teach a morning of religious school to 9 year olds? Or visit and observe a public school for a morning?
Smiles,
Grinity
Bottleneck= a learning challenge that is still in the normal range for age but causes a gifted kid to have a noticeable daily challenge.
