There's a really good recent book a bit along the stuttering issue line. Check out "Out with it" [https://www.amazon.com/Out-Stuttering-Helped-Find-Voice-ebook/dp/B008J4RTGW](https://www.amazon.com/Out-Stuttering-Helped-Find-Voice-ebook/dp/B008J4RTGW) It's a good self-helpy-story book. I'm not sure how to wrap my head around the idea of a fiction novel. I think I'd want it to focus on the cognitive/affective aspects of stuttering and not just the overt speech.
