telling a friend about the sound of a wild snail eating made me go back to the webshop where i bought it ( https://libro.fm/audiobooks/9781399419017-the-sound-of-a-wild-snail-eating ) and noticing it's not even marked as a book about disability.
No wonder I hardly ever stumble upon books about/from bedbound people.

Aside from the book I just mentioned the only other example I can think of now is 'we are the winter people', a poetry collection by Jenny Rowbury.
