A Newbery Honor BookAn ALA-ALSC Notable Children's BookWinner of the Edgar Allan Poe Award for Best Juvenile Novel "An adventure, a mystery, and a love song to the natural world. . . . Run out and read it. Right now."--Newbery Medalist Karen CushmanIn the town of Placid, Wisconsin, in 1871, Georgie Burkhardt is known for two things: her uncanny aim with a rifle and her habit of speaking her mind plainly. But when Georgie blurts out something she shouldn't, her older sister Agatha flees, running off with a pack of "pigeoners" trailing the passenger pigeon migration. And when the sheriff returns to town with an unidentifiable body--wearing Agatha's blue-green ball 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 will track every last clue and shred of evidence to bring Agatha home. Yet even with resolute determination and her trusty Springfield single-shot, Georgie is not prepared for what she faces on the western frontier.
