 In the book, Piotrowski attempts to redefine the Holocaust so that it is expanded to include all "systematic genocidal victims" of the war.The book is not organized chronologically but by cultural coordination/collaboration between ethnic groups, which Romanianko writes provides a refreshing departure inhibiting further ill feeling regarding the role of Ukrainians, Russians, Germans, Poles, Jews, Lithuanians and Belorussians in Holocaust on territory of Poland; although Piotrowski's research indicates that involvement of each group in victimising Polish Jews and Catholics was at times ubiquitous, he prohibits widespread censure of entire cultures.Romanianko states that Piotrowski's book is one of the most comprehensive and well documented, multi-methodological contributions to scholarly work in the area."
