Unbreakable

The edge-of-your seat true story of the codebreakers, spies, and navy men who cracked the Nazis’ infamous Enigma encryption machine and turned the tide of World War II-perfect for fans of The Imitation Game. As the Germans waged a brutal war across Europe, details of every Nazi plan, every attack, every troop movement were sent over radio. But to the Allied troops listening in-and they were always listening-the crucial messages sounded like gibberish. The communications were encoded with a powerful cipher, making all information utterly inaccessible … unless you could unlock the key to the secret code behind the German’s powerful Enigma machine. Unbreakable tells the true story of one of the most dangerous war-time codebreaking efforts ever. While Hitler marched his troops across newly conquered lands and deadly “wolfpacks” of German U-Boats prowled the open seas, a team of codebreakers, spies, and navy men raced against the clock to uncover the secrets that hid German messages in plain sight. Victory-or defeat-in World War II would hinge on their desperate attempts to crack the code. Unbreakable is a groundbreaking work of narrative nonfiction from the author of Race to the Bottom of the Earth (recipient of four starred reviews)-perfect for fans of Bomb, The Boys Who Challenged Hitler, and The Nazi Hunters.
