books like johnny got his gun

hello all! i just finished johnny got his gun and it very well may be my favorite book. i was highly interested from the premise alone, a deaf, blind, mute quadriplegic. its a somewhat simple book, with very few characters and virtually no setting. i loved reading these stream of conscious rants about time, love, what it means to be alive, etc. the ending was also incredibly powerful, i loved the harsh reality of the the military and the anti-war socialist message. im kind of rambling for my love of this book, haha. just trying to give a sense of what i find so appealing about it. a book i think is kind of similar was metamorphosis, which i also loved. theyre both pretty short books, take place mostly inside the protagonist's head, and deal with illness and capitalism. let me know of any recommendations. thanks!
