This book is a Newbery Medal winner, and for good reason. It is another book that I was unable to put down once I started reading it. Annemarie is the main character, and she has a best friend, Ellen, that is moving in and pretending to be part of Annemarie's family in order to keep her safe. This is because Ellen is Jewish and the Nazis are coming in and removing all of the Jewish people. Annemarie ends up having to go on a very risky and dangerous mission in order to save Ellen's life. It is a fast read, and it will keep you on the edge of your seat. It is a powerful reminder of the horrible things people went through during the Holocaust.
