Summary, etc.:
"A nonfiction manuscript for young readers about a group of Allied spies and codebreakers that cracked the Nazis's infamous cypher, allowing them to read secret military messages and turn the tide of World War II. During WWII, as the Germans waged war, every Nazi plan, every attack, was sent over radio. But to the Allies listening in, the messages sounded like gibberish. The communications were encoded with a powerful cypher-unless you could unlock the key to Germany's Enigma machine. Featuring historical photos, Unbreakable tells the story of one of the most dangerous war-time code-breaking efforts ever. As Hitler marched his troops across conquered lands and deadly "wolfpacks" of German U-Boats prowled the open seas, victory-or defeat-for the Allies hinged on their desperate attempts to crack the code. Told in riveting multiple points of view, Unbreakable is perfect for fans of The Boys Who Challenged Hitler and The Nazi Hunters"-- Provided by publisher.
