Yes! I would just give you the advice to write very carefully so you don‘t make a book that‘s boring for non stutterers because it only contains information for stutterers or boring for stutterers because it contains a lot of things they already know. Also: as someone who has been to a bunch of speech therapists and dealt with a bunch of ignorant people (haven‘t we all?), I think they could really benefit from a book written by someone who stutters. Some of them have no idea what we go through. Good luck and let us know how it is going!!
