Self-help books for teenage girls

[singforsupper]

I'm looking for something that will help my daughter get through:

a) confusing world of media, technology, porn
b) recognising relationships based on power/insecurity/abuse or even love.
c) anything that I can read as a parent to help her with the above.

There's another thread on fiction for teenage girls - this one is for self-help.

I've already heard that Kim Cattrall's book is good.

I recently ordered a book by Kaz Cooke for my soon to be 13 year old - its subtitle should be "the bible to teenage years", just amazing, covers everything from puberty to 20 ways to say no .... really wonderful book
