I would write the books. Doing so would likely help you heal, help other people, and expose your abusers for the subhuman filth that they are.

Besides, what are the worst that your abusers could do if you did this? If they try to start something, get a restraining order on them. If they attack you or harass you, call the police on them. You have all of the power here.

I would publish the book and write more books. Do what you need to do for you and screw those idiots.
