Mrs. Sookie Poole, of Point Clear, Alabama, has just married off her daughter and is looking forward to relaxing. The only thing left to contend with is her domineering mother, the formidable 90-year-old Lenore Simmons Krackenberry, who is obsessed with family lineage and Southern heritage. But when Sookie receives a series of mysterious letters that suggest that she’s adopted, she is sent down a rabbit hole of self-discovery, ultimately uncovering the swashbuckling story of Fritzi Jurdabralinski and her sisters, a daring group of women who ran the first All-Girl Filling Station during WWII and ultimately became the first female Air Force pilots.
