This is a class set of 20 books. This is the story of a family -- a mother and father and their two young children--who became trapped in Hitler's Germany. They managed eventually to leave that country for Holland, where they were soon again caught in the Nazis' web, and their situation grew even more serious. For in the final years of World War II, when the Holocaust reached its most feverish pitch, the four members of the Blumenthal family were returned to Germany.
