Not so sure about this one ... I plodded through to the end but it did feel unremittingly grim (and a bit boring and repetitive!). The premise is, what would have happened had Anne Frank survived the death camps and been reunited with her father and her diary? I'm not convinced that anybody has the right to take ownership of Anne's story ... let's leave her the truth of her own life and death, at least. She could conceivably still be living today.
The atmosphere of post-war Amsterdam was interesting, though - and the extraordinary fact that the Franks might well have been deported back to Germany.
