London schoolgirl Hettie hears the whispers and sees the worry creeping
across her parents' faces. She watches as the windows in her home are
blacked out. She helps her dad build a bomb shelter. She learns how to
wear a gas mask. War, led by Adolf Hitler, is stomping its feet at Great
Britain's doorstep, and Hettie knows only one thing for certain: When
the bombs come, it will take all the courage she has to be brave and
survive.
