Query: Must read for anyone with teenage girls

I read this when my niece was going through "terrible teens" it was such an eye opener and helped me understand my niece when she was very unhappy and difficult.if you do not read this and have daughters I feel you are doing them a disservice, it is ESSENTIAL.My niece is now a very strong woman. This book helped me help her.
