This was a highly readable book about the differences in the brains of adolescents vs children and adults. The brain goes through a lot of changes and that correlates with the changes in behavior and risk taking we often see in teenagers. The author encourages us to see adolescence as a unique time when the brain changes a lot and not think of it as a deficient time. Adolescents are not just “bad” adults. The chapters are short and full of research that is easy to understand. I really enjoyed this book.
