Based on a true story Prisoner B-3087 tells the journey of Yanek Gruener, a jewish boy who lives in Krakow. When he is 10 years old the German march into Poland and his life changes forever. He and his family are moved into the Krakower ghetto where they share a house with other families. Later the Gruener family is separated and brought to different concentration camps. Yanek meets his uncle again in one of them, who tells him the only important thing now is to survive. Yanek passes though 10 camps all together among them well-known ones like Auschwitz, Bergen-Belsen, Buchenwald, Sachsenhausen and Dachau. The reader get's an inside view on the feelings which prevailed during the time, the hope the prisoners kept for more than 5 years even thought the cruelty was barely bearable. It is an emotional and touching read which let's the reader re-live the time during Wold War II.I personally found the story a little shallow. I was hoping for more depth and felt like the story was rushed. What happened in between the different camps? The storyline in each camp was a little short and could have been deeper. Since the author explains that the book is a work of fiction nevertheless, he could have added more to it.
