Fiction by Maria Hummel.
Set in Germany at the end of of World War II, this is a fictionalized account of part of the author's own family history, based on some of her grandparents' letters she'd found hidden in a wall for fifty years.
The novel explores the idea of Nazi Germany: How much did ordinary, regular people really know about the horrors of the Holocaust? Was everyone really buying into cult of Der Fuerer, and the idea of the Master Race? The citizens endured countless sufferings and losses. Can the Germans' troubles be discounted because they brought it on themselves?
It's a really good story, but we all know there was no happy ending for the Germans. And this story does not have a happy ending.
