The Editors Andrew Moskowitz, PhD, Professor of Psychology, Dean of Undergraduate Programs, Touro College Berlin, Berlin, Germany. Martin J. Dorahy, PhD, Professor of Psychology, University of Canterbury, Christchurch, New Zealand. Ingo Schäfer, MD, MPH, Professor, Department of Psychiatry and Psychotherapy, University Medical Center Hamburg-Eppendorf, University of Hamburg, Hamburg, Germany. The painting on the front cover, Composition VI, was created by Wassily Kandinsky in 1913. Inspired by the Biblical story of the Great Flood, Kandinsky drew on themes of destruction and rebirth in developing these images.

“This volume is highly recommended to clinicians and researchers as an excellent resource of contemporary thinking in understanding some of the many complex ways that individuals respond to traumatic experiences” - Pamela R. Fuller, Fronteir Psychological AssociatesPTD includes outstanding contributions from international experts and provides a comprehensive view of its topics, particularly with respect to conceptual and research issues. The editors have interspersed throughout the book parentheses leading the reader to other related chapters, but a summarizing contribution would have been welcome. That small qualm notwithstanding, PTD is essential reading for anyone wanting to understand how trauma, dissociation, and psychosis both  converge and diverge.
