I've never actually read Twilight. I didn't have to because my roommate read all four books and I could just kind of ride along.

The spoilery thing is how Nick really really wants to make Alan's leg better. And how it emerges through the book that the person this is about is Nick, not Alan. And then that perfect moment when Alan's leg reverts back, and he just kind of shrugs and says well, he was used to it, and it's part of him now. That just rings so true to me -- that it is the nondisabled character who can't cope with the disability, and the disabled character who has a complete, integrated identity around it.

Thanks for the link -- I hadn't read that since I was avoiding spoilers for this like crazy.
