I do not recommend this one.
Goodnight, Vienna, is the story of a Russian emigrant turned British governess, and her Austrian charge, who flee after the Nazis take over Vienna and all of Austria. I've thought a lot about this book since I finished it, trying to pinpoint why this did not work for me. While I think the effort was for a story arc of overcoming adversity and one of survival against repeated overwhelming odds, I think the story spent too much time buried in the adversity and very little time making me care about the characters except for in context of what was happening to them.
The writing was better when discussing some really horrible people and their revolting beliefs. The villains are more brightly drawn, such as Dr. Asperger and the Nazi commanders that show up repeatedly. That's not to say there aren't amazing and amazingly good people on the right side here. Specifically, I think Hildegard, the music student in Innsbruck, and the doctor, David, and his sister, Shulamit, were characters that were not as one dimensional. Though each had a relatively short time on the page, they had huge impact on Katya's and Gretchen's safe escape. That's great. But there was so much negative that ate up the pages, it was hard to find anything positive. Katya felt very determined but never very warm. Gretchen is a child struggling with the loss of her mother, a severe learning disability, possible neurodivergent behavior, and a magnificent musical ability. I saw more growth in the Gretchen character, but there was little in her POV. I think that would have been helpful. For example, her thanks in the prologue, to those that helped her, that showed her growth and character. But it's at the end!
And repeatedly over and over, the two of them escape the Nazis. Over and over and over. And the number of times someone said, just go, leave, and that's how they escaped? It just kept happening.
Instead of the persecution of Jews, the author focuses mostly on the Nazi plans to cleans the Aryan race of those who were not physically perfect. Gretchen herself is a target of this program because of her neurodivergence and dyslexia. Through the story multiple characters are subject to horrific treatment solely because of their disabilities. And yes, this absolutely was a component of the Nazi programs. The parade of disabled characters that Katya and Gretchen connected with, and who were then murdered by Nazis, began to wear on me as a reader. Georg and Shulamit are both well drawn initially, and while Shulamit helped Katya and Gretchen reach Switzerland successfully, both Georg and Shulamit were ultimately only victims. They existed mostly to be killed, it felt. And that was so disappointing.
I do not recommend.
