Going into Germany during the war? How can you even think that will be safe and with a civilian in tow?

Nathan is to enter Germany and find out secrets about how far the Germans are with an atomic bomb and to bring back a German scientist to the United States. He is to take physicist Allison to be sure they are getting the correct information.

Nathan is undercover as a high-ranking German officer and Allison is to be his girlfriend.

How safe can this be? Allison is very frightened.

We follow them on their journey and learn a great deal about physics and the building of bombs and feel the tension as they are interrogated by other German officers that are questioning the validity of Nathan’s rank.

The technical aspect was not of interest and I was hoping it wasn't going to be that detailed throughout, but Mr. Balson as always has a story line that is outstanding and pull you in with two main characters you will love.

The tension as Nathan and Allison do undercover work and deal with the Nazis had my heart pounding.

Another marvelous, well-researched book by Mr. Balson. 4/5

This book was given to me by the publisher via NetGalley for an honest review.
