Query: The only safe place was upstairs

The story takes place during the Second World War, from 1938 through 1945. In Winterswijk, close to the Germany border. Annie and her dad listen to the radio a lot to hear about all of the news that's going on. Annie's mom and dad argue a lot. Annie is eight years old in the beginning. Rachel, Annie, and Sini are all sisters. They are also all Jewish. After the war started Annie and Sini go live with the Oostervelds, and they stay in their upstairs room for two years. While they were there their mother died. The Oostervelds are Opoe, Johan, and Dientje. I liked this book because it explained how the war was back then, and a lot of details.
