Absolutely unthinkable

I was so caught up in Yellow Star by Jennifer Roy that I read it in one day.  In 1939 Lodz, Poland, was invaded by the Germans, and all of the Jews were forced to move to a certain part of the city, the ghetto.  Over the years, more than a quarter of a million people were sent to the ghetto, but when it was liberated in 1945, there were only about 800 survivors, twelve of whom were children.  This story is told in free verse, and it's based on the the actual survival story of Sylvia, one of those children and the aunt of the author.  The horrific sights and sounds, the terror of being sent to the trains, the fear and hope...told through the voice of a child was mesmerizing.
