The book is written with astonished and called objectivity. There are good Jews and bad Jews in the film. And that's how it was. There are good Germans and bad Germans. There are good Poles and bad Poles. And above all the book is tremendously optimistic. The victim survives. Survives thanks to his passion for the.. for the art and for the music in particular. Thanks to his willpower. It's an optimistic and uplifting book in spite of the horrors that it describes.
