I read this book several years ago; I loved it then and I continue to recommend it to parents as a great guide to understanding the world of girls.   I also saw Rosalind Wiseman speak in person several years ago, and I found her to have a down to earth, practical and reasonable approach to working with kids in these tough relational situations.  She doesn’t claim to have all the answers or say that these things won’t happen.  But she does have some ideas of how to work through things and is great at explaining things in a way that  parents understand.
