The boy who dared Summary

In my book "The Boy Who Dared", by Susan Campbell bartoletti, the main character is a guy named helmuth who grew up in a time when hitler rose to power. Throughout the book, there are flashback sections to when he was a kid growing up in that time and sections in the present where helmuth is in prison for a currently unknown reason. Helmuth grow up with two half brothers named Hans and Gerhard, a single mother whom he calls mutti, who grandparents he refers to as oma and opa. His father was never present in his life and his two brothers have a different father than him but both men who have had kids with mutti  are not in the picture. Helmuth grows up with the terrible discrimination that Adolf Hitler brought towards the Jews in Germany.  He has seen nazi brutality on Jews who tried to clean graffiti that was being written on their homes and shops. Helmuth wasn't able to shop at any Jewish stores or markets because Germans were forced to not spend money at Jewish establishments and only at German shops.
