Number the Stars by Lois Lowry

This historical fiction follows young Annemarie Johansen as she does what any good friend would do, even when it's not the easy thing to do. Nazi-held Denmark in 1943 is enough information to tell you the basic premise for the story. The history lesson is well done and the storyline is emotional and enthralling. Highly recommended.

Note for Parents/Teachers: This one is geared toward kiddos. It would be great for a lesson on WWII or a lesson on standing up for what you know is right even when it's difficult or dangerous.
