Anne Marie is a young, German girl. She is aware of the war going on around her, and she knows enough to be afraid of the soldiers she sees.
She changed quite a bit from the beginning of the story to the end. In the beginning, she was naive. I think this, because on page XX, she didn't understand what was happening to the owner of the button shop. By the end of the story, she was brave, and had a better understanding of the war. One example of this was her understanding that there was no Aunt Birte. I aslo know this, because she risked her life and lied to Nazis in chapter XX, in order to deliver the important package.
I also think she is an incredibly loyal friend that would risk her life to protect Ellen. One example of this was not telling Ellen about Aunt Birte on page XX. She did this to protect her. She also showed her loyalty when she lied to the Nazis. She could have died, but risked her life to get to her uncle's boat.
