“Good news! This is the most comprehensive volume written to date about friendships in childhood and adolescence. The book has a clear-cut developmental point of view and deals with both friendship dynamics and the significance of friendships in individual lives.

“This clear and authoritative book is a splendid resource for all those interested in children’s friendships—their drama and excitements, pleasures and problems. It covers a broad range of topics with exemplary thoroughness; where the research findings are inconsistent, the authors keep a sharp eye on the empirical evidence. The focus includes topics of clinical interest, such as attachment relationships, antisocial and aggressive behavior, deviance, and what is known from intervention studies. Most strikingly, the book highlights key questions raised by the research findings and by the gaps in what we know. This questioning approach makes it a stimulating read, of real value for upper-level undergraduates, graduate students, and their teachers.”

“This beautifully written book illuminates the ordinary magic of children's and adolescents' friendships. The book integrates diverse theoretical perspectives and the sprawling research literature on friendship in an accessible, engaging manner, with lively examples all along the way. It will be of great interest to everyone who seeks to understand children's friendships: researchers, clinicians, students of social development, educators, and all who desire to foster positive relationships between young people. It is also well suited as a text for undergraduate and graduate courses on social development and seminars on friendship and close relationships.”
