War isn't just fought on the battlefield. During the Civil War, a hidden war was raging-one of spies, secret codes, and daring missions that shaped the outcome of history. While armies clashed, ordinary people became undercover agents, slipping behind enemy lines, stealing battle plans, and risking everything to pass along critical information. Men, women, and even children worked in the shadows, hiding messages in dresses, writing in invisible ink, and using disguises to outsmart the enemy. Some were caught and thrown into prison, while others disappeared without a trace. Their names and missions were often left out of history books, but their actions changed the course of the war. Packed with real-life spy stories, this book takes young readers deep into the world of Civil War espionage. From daring escapes to double agents, from secret codes to balloon surveillance, it reveals the tricks and tactics spies used to stay hidden-and the risks they faced if they were caught. Perfect for young history lovers, this book isn't just about reading the past-it's about stepping into the shoes of the brave spies who lived it. Who sent messages in hollow eggs? Who stopped an assassination plot? Who never got caught? The answers are waiting inside.
