The Stuttering Foundation of America has some great resources. Check out their website, and they also have some books. I would recommend Advice to Those Who Stutter. Here’s a link: https://www.stutteringhelp.org/free-e-books And not a book, but I HIGHLY recommend the StutterTalk podcasts. There are so many episodes to sort through but you can search on their website and find ones that are interesting to you. There’s a lot of episodes that are people just sharing their experiences with stuttering. https://stuttertalk.com/
