This is an important and timely resource for scientists, practitioners, and policymakers interested in applying the science of adolescence to a wide range of issues that impact the health and well-being of the world's youth. It combines up-to-date reviews of research on adolescent development by the world's leading authorities with thoughtful discussions of some of the most pressing concerns that societies face in both developed and developing countries in their efforts to minimize problematic outcomes and maximize positive development during this critical stage of development. I recommend it highly.
