Despite a serious amount of visual information which of course I miss, I managed to enjoy this book tremendously. I think the appeal for me is the very logical way in which Christopher approaches the world, it doesn't feel as if you're being told about disability, rather that you are perceiving the world in a way this young man lives it, in a direction so different from that our collective consciousness expects us to face. It's not a long read but it's seriously worth more thought per page than many books I've found.
