In 1871, in the town of Placid, WI, 13-year-old Georgie Burkhardt is known for two things: One Came Homeher uncanny aim with a rifle and her habit of speaking her mind plainly. But when Georgie blurts out something she shouldn’t have said, her older sister Agatha flees, running off with a pack of “pigeoners,” who follow the migration of passenger pigeons. When the sheriff returns to town with an unidentifiable body—wearing Agatha’s blue-green ballroom gown—everyone assumes the worst. Except Georgie. Refusing to believe the facts that are laid down (and coffined) before her, Georgie sets out on a journey to find her sister. She’ll track down every last clue and shred of evidence to bring Agatha home. Yet even with her resolute determination and her trusty Springfield single-shot, Georgie isn’t prepared for what she faces on the Western frontier.
