The past haunts the present

THOSE WHO SAVE US by Jenna Blum
Family secrets of Nazi Germany are at the core of this powerful first novel told in two narratives that alternate between New Heidelberg, Minnesota, in the present, and the small town of Weimar near Buchenwald during World War II. Trudy is a professor of German history in Minnesota, where she's teaching a seminar on women's roles in Nazi Germany and conducting interviews with Germans about how they're dealing with what they did during the war. But her mother, Anna, won't talk about it, not even to her own daughter. Trudy knows, she remembers, that Anna was mistress to a big Nazi camp officer. Why did she do it? Was he Trudy's father?
A great book for discussion groups and a wonderful study in how our past influences our present.
