With all the men off to war, Fritzi and her sisters must learn men's work, from fixing flats to driving the tow truck. Wearing smart little caps, short skirts and roller skates, they fly round the forecourt of The All-Girl's Filling Station. But it's wartime, and the sisters' peace won't last long. In Clear Point, Alabama, the only war Mrs Sookie Earl knows about is the one she's waging against the Blue Jays in her garden. But then one day a package arrives. Its contents knock Sookie sideways. Feeling like a stranger in her own life, Sookie's search for answers takes her back to the 1940s and four irrepressible sisters whose wartime adventures force them to reimagine who they are, and what they are capable of.
