Uhh it's a good idea and I would probably want my kids to read it when they study WWII, but there are some big problems with the character development, among other things.

The biggest problem I have is with the last line: "Of course all this happened a long time ago and nothing like that could ever happen again. Not in this day and age." Uuuhhhmmmm hello, it is currently happening in North Korea, and genocides are happening in other countries. That's the problem. It is happening and will most likely happen again.
