I recommend "Extreme Defense", a military-spy novel. Although the plot doesn't completely revolve around the Cold War between the United States and the Soviet Union, the story in the book takes place during the Cold War. Under the shadow of the two superpowers, it reveals the identity of the protagonist and his responsibilities. This novel is unique and will definitely make you feel the beauty of military spy warfare. I hope you like this fairy's recommendation. Muah ~😘
