I have a stroppy teen and have tried everything in the book, so when she actually liked this book, I was shocked. She found it very helpful and although she is still in that difficult growing up stage, she has calmed down a little. Any parent pulling their hair out this book helps. Lana (whoever she is I don't know) but she provides help with worries, helps to find happiness, touches on yuk stuff like drugs but then this is needed these days. I read it myself and found it very good for me as well.
