Summary: Felix is lucky. Unlike the other children in the orphanage, he's certain his parents will come back for him. And whatever the Nazis do and however many books they burn, Felix's imagination provides him and his companions with stories that protect them when they're on the run, and give them hope when all seems lost, and one day may even save Felix's life.
