I am not aware of any on SZ, but I will look. I don't know if this would pertain b/c I don't know much on SZ but there is a good book out there for families of borderlines called "sometimes I act crazy." Not sure if this helps at all. I hope someone else comes along who knows more than I do. And best of luck to you.
Found this site:
