Prisoner B-3087 is a historical novel based on the life of Jack Gruener, also known as Yanek. Yanek lived in Poland during World War II and was 10 when his hometown of Krakow fell to the Germans. He quickly becomes separated from his family and has to endure the unbearable conditions of numerous concentration camps that include the infamous Auschwitz and Dachau. Yanek is finally liberated at Dachau as a young adult when the Americans take control. This book really describes the lives of those who had to bear the conditions of the Holocaust and Yanek’s story of surviving so many camps. This book is a wonderful read to those who like reading books about World War II, and certainly for those who enjoy reading Gratz’s work. As for me, I personally really enjoyed this book and would definitely recommend it.
