I really like this book at help me through so much. Originally started reading it for Girl Scouts, but then my troop split up and I still have the book; I started reading it just for fun and I found it helped me so much.
This book is filled with helpful advice, stories, guidance and interesting activities that engage teen girls in how to navigate friendships and other relationships. Building healthy relationships is crucial, a skill that will take young girls into adulthood with more confidence and social capital. I found this book to be very useful for supporting girls in this regard, whether in Girl Scouts or not (just ignore the few GS-specific references).
