Marcel Lebrun’s latest book provides a panoramic view of juvenile violence in the U.S. and beyond—violence in which children can be victims, perpetrators, or both. Unsparing in its detail, the issues that Dr. Lebrun explores will disturb every reader who is concerned with the safety and well-being of the youngest and most vulnerable members of our society. More than mere description, this book is a call to action, offering recommendations and reminding us that how we treat our children is a key to the future of our nation.
