it's not normally diagnosed in children, at least it didn't use to be because it's a personaltiy disorder and most psychiatrist won't dx it until you've turned 18 and your personality is pretty much fully developed

i guess i should add it can be dxed in people your age, since you're in your late teens and you are close to an adult, but i don't believe there are any books written about it, but i can tell you some books that are good for pretty much anyone with BPD if you'd like????

I agree with the person above me. BPD usually isnt diagnosed in children. Here are two things you might want to look at though:

"Get Me Out of Here" and "I Hate You, Don't Leave Me"

Actually, in worth cases Borderline symptoms can be early teenage years. But if that is the case, your child needs professional support rather than books!
However, to get to your question, try "stop walking on eggshell" (there's the patient and practitioner editions). Also "sometimes I act crazy" is really good as, not only it explains the reason of borderline PD, it give good practical advices for both sufferer and people living around a BPD. My best read in my disorder!
Good luck
