When Hitler Stole Pink Rabbit — Judith Kerr

Anna is only nine years old in 1933, too busy with her schoolwork and friends to take much notice of Adolf Hitler's face glaring from political posters all over Berlin. Being Jewish, she thinks, is just something you are because your parents and grandparents are Jewish. But then one day her father is unaccountably, frighteningly missing. Soon after, she and her brother, Max, are hurried out of Germany by their mother with alarming secrecy.

Reunited in Switzerland, Anna and her family embark on an adventure that will go on for years, in several different countries. They learn many new things: how to speak new languages, how to cope with the wildest confusions, and how to be poor. Anna soon discovers that there are special skills in being a refugee. And as long as the family stays together, that's all that really matters.
