Sookie Simmons Poole has launched her adult daughters and is now responsible only for her aging and temperamental mother, who lives right next door. When Sookie gets a packet of letters in the mail, it opens a host of questions about a past she never knew. The letters document the story of the Jurdabralinski sisters, who take over the family filling station when World War II starts. But eldest sister Fritzi wants to do more to serve, so she becomes part of a pioneering unit of women pilots. Flagg has told a story that is part mystery and part history, but all about indomitable women. Given in memory of Anne DeGise by her daughters, Rosanne O'Neill and Jan Sarmiere.
