'Edited by a world-leading authority, this one-of-a-kind volume is an invaluable resource for all scholars studying how violence develops early in life, and what we can do to stop that progression. Academic books are rarely page-turners, yet this one is. It is at once a heart-rending, educational, and fun read. It has my highest recommendation.' Adrian Raine, Richard Perry University Professor of Criminology, University of Pennsylvania
