Written for all teen girls, this insightful book discusses different types of girl-on-girl cruelty, why it happens, and how to deal with it. With details on various forms of abuse common between girls—including betrayal between friends, cyberbullying, hazing, and the silent treatment—this useful guidebook will help teen girls understand why they show aggression to each other, cope with difficult situations, gain confidence, and work together as teams, while also suggesting when to get help from adults when situations get out of hand. It includes quotes and inspirational stories from famous role models who have had firsthand experience with girl meanness, such as Jane Wiedlin, founding member of the Go-Go's; Jenny Conlee, bandmember of The Decemberists; and Tegan, bandmember of Tegan and Sara.
