The true stories forgotten by history are some of the best inspirations for novels. Amy Stewart uses Girl Waits With Gun to revisit the story of Constance Kopp, one of America's first female sheriffs. After being subjected to a barrage of criminal retaliation over a minor traffic incident, Constance teams up with the local sheriff to assist in holding the culprits responsible. Even better: she teams up with her sisters, too, for some good old-fashioned girl power.
