War books for young adults?

Hey guys I`m 14 an I love reading ww2 books and books on labour camps in the soviet union and Nazi Germany. I have read One day in the life of Ivan Denisovich by Alexander Solzhenitsyn, Hitler by Albert Marrin, Stalin by Albert Marrin and Animal Farm. Soon I`m going to read Mein Kampf by Adolf hitler, Spymaster by Oleg Kalugin and The Mitrokhin Archive. I am also reading Socrates the man who dared to speak. Do you have any other ideas on books I could read for young adults? Your help is greatly appreciated!
