es significant advances in neurobiological research over the past decade, and includes a new introduction by Dr. Vincent J. Felitti, a leading researcher in the field. When Ghosts from the Nursery: Tracing the Roots of Violence was published in 1997, it was lauded for providing scientific evidence that violence can originate in the womb and become entrenched in a child's brain by preschool. The authors' groundbreaking conclusions became even more relevant following the wave of school shootings across the nation including the tragedy at Columbine High School and the shocking subsequent shootings culminating most recently in the massacre at Sandy Hook Elementary School in Newtown, Connecticut. Following each of these media coverage and public debate turned yet again to the usual suspects concerning the causes of violence: widespread availability of guns and lack of mental health services for late-stage treatment. Discussion of the impact of trauma on human life--especially early in life during chemical and structural formation of the brain--is missing from the equation. Karr-Morse and Wiley continue to shift the conversation among parents and policy makers toward more fundamental preventative measures against violence.
