This is sort of a long picture book... a juvenile nonfiction.
It's also a really unique look at the Holocaust.
Bouncing between Hana's story in the 1930's and 40's and the story of the Japanese woman who brought Hana's story to life, we learn more about Hana's childhood than her time in Auschwitz. And that totally works.
Apparently the Holocaust isn't something taught much in Japanese schools, but there is a museum set up to teach children in Japan what happened. When the museum receives a suitcase with the name Hanna Brady on it, the children want to know who she was.
A really fabulous book. HIGHLY recommended.
