Papa is in danger for helping to rescue a free-state settler who was unjustly arrested by Kansas's proslavery sheriff. He has gone into hiding, and Momma and the Keller children are alone in their remote cabin while marauding border ruffians are roaming the countryside, looking for livestock to steal. But there's a lot more at stake at the Keller homestead than their chickens and cows. Charlie has come upon Lizzie, a runaway slave girl trying to make her way to freedom in Canada, and the Kellers are hiding her at their cabin. With the violence in Kansas Territory escalating, the Underground Railroad isn't running. Can Charlie and his family keep Lizzie safe until she can escape from Kansas?
