When Polly's father goes overseas to fight in World War I, her whole world changes. Though the war is in Europe, its effects are felt on American soil. There are food, fuel, and other supply shortages everywhere. Even something as simple and enjoyable as a family Sunday car ride isn't possible anymore.
Everyone must do their part to help the war effort. Victory gardens are planted and scrap metal is collected. It's the biggest event in our history. And it involves every single adult, every single boy, and every single girl, says Polly's teacher.
As Polly struggles to make sense of the war, she wonders how she can contribute. When the government puts out a notice requesting peach pits to be used in gas mask filters, Polly knows how she can help and organizes her Girl Scout troop into a parade where everyone can contribute their peach pits to the war cause. This uplifting telling of a little-known story of World War I is a celebration of communities coming together in times of greatest need to protect the people they love.
