An Affair of Spies by R.H. Balson, published by St. Martin's Press, is a full-length, historical novel.
The storyline is set in the 1940ties at WWII in the USA.
The US are at war with Germany and it's allies. Immigrants had to flee from the regime fearing for their lives.
The book paints an intriguing, raw and gritty picture, a story that checks all my boxes, 4,5 stars.

I was delighted to have the opportunity to read an advance copy of this book thanks to the publisher and Netgalley. I loved the book and could hardly put it down. It was a departure from Balson's usual legal thrillers (which I also like), but this one was an intense and unique spy thriller. The premise of a Jewish refugee from Germany, now in the US Army, and an American female physicist entering Germany during the war to extract a German physicist and learn about Germany's progress with nuclear bombs was very exciting. The author did a great job explaining the fundamentals of nuclear power in an understandable way. I could imagine this book transforming into a great movie. I highly recommend this book and look forward to Balson's next one.
