I ordered a copy of this book as I am very interested in learning more about how girls interact as I have daughters myself. This book talked about some very important facts, but the overall tone of this book was quite negative. I felt like this book did a lot of explaining how and why girls are mean and unkind, but didn't do a lot to explain how to cope or fix the problem. Overall, I didn't find this book to be a very valuable resource in helping the problem, but one that shows what you need to look out for. The advise it does include should be taken with a grain of salt.  It is very long and hard to get through. I received a copy of this book for free from Blogging for Books in exchange for my honest review.
