A very well written and moving young adult book which tells the story through the eyes of a young dutch woman living in Nazi occupied Amsterdam. The characters were engaging and realistic, they gave me a good insight into what life was like for young people at that time. There were some notes on historical accuracy at the end which made the story even more poignant. I feel that the sadness of the book and the emphasis on relationships would probably be more of interest or suitability to a slightly older teen, perhaps 14 or 15, but nothing in the book that is really unsuitable for a younger reader. I feel the story would have benefited from hearing a voice from some of the Jewish characters. The fact a young adult book is a good read for an adult says a lot about the quality of the book. My copy came from the library and was classified as historical rather than young adult.
