This book may be one of the most important contributions to EMDR therapy literature so far in this century. Nickerson has astutely gathered together a collection of compelling articles that highlight the struggles of individuals and groups who have tragically and traumatically been affected by discrimination and discusses how EMDR therapy may be utilized to help them heal.

After reading Nickerson’s compelling and boldly comprehensive text, I have found myself sitting with clients in an entirely new way and so will you. With the multiple lenses offered in this book, you will start to think differently about the ways in which diverse cultural factors – social class, ethnicity, race, sexual orientation, religion, immigrant status, gender, discrimination, prejudice, and various disabilities interact to shape beliefs about oneself and one’s experiences in the world.
