After seeing the film, I wanted to read the book to see how faithful an adaptation it was, elements of the story are unbelievable! My conclusion is that the film is faithful and an excellent exposition of the story. I wanted to know more about the German Officer (Hosenfeld) that the author has a pivotal meeting with towards the end of the story, the book has an epilogue that tells more about Hosenfeld with extracts from his diary, and some extra source material. This extra perspective is another layer to an incredibly harrowing and miraculous account of a survival in the Jewish ghetto in Poland, a beacon of humanity in a dark time. Looking at other reviews, people have commented on the emotional detachment of the author, what is interesting is that the author wrote the book immediately after the war, it was published in 1946 under a different title, when nobody was keen to hear more about the horrific recent past. Reading it with this in mind, it emphasizes the shock that the author must have still have been suffering from all the trauma endured, other holocaust accounts with more time passed are probably more emotional accounts, that made it more poignant for me. It is an excellent read about a grim period of history but with enough humanity throughout to make it digestible
