We have an additional entry on our Mind Meld on Disabilities in Speculative Fiction, from Nebula Award winning author Vylar Kaftan!
I think the Kaleidoscope anthology is worth mentioning here. It’s a new YA anthology focused on diversity in middle grade and YA fiction. Several stories include disabled characters (both mentally and physically).
I don’t have a specific disability that I’d like to see done well, but I do urge writers to research disabilities and get them right. This often means talking to more than one person. One of the common things with disability is that two people with the same medical condition can have very different experiences for other reasons, such as the intersection of two disabilities making it all worse, or the person’s financial ability to deal with the disability. It makes a big difference if you can afford truly accessible living space, for example, or to pack and carry all your own food everywhere you go.
