Ever wonder what would happen if your world turned upside down in only a few minutes? That's the dilemma for fifteen-year-old Meagan Mast, violently left an orphan on the 1858 Nebraska Plains. She soon finds herself with Sir, a man that heals and kills with equal ease, watching life unfold around her, and praying to return to her Amish lifestyle, upbringing, and the Amish farmer she loves. Meagan finds it difficult to have an Amish lifestyle and still survive as settlers, soldiers, Indians, and other assorted characters invade her daily life. Her problems get worse when she rescues Katherine Smith from trouble. Far from happy over the rescue, Katherine thinks Meagan should die and leave her alone, a process Katherine tries to help along. The opposite of the Amish Meagan, Katherine finds lying, stealing, and whoring a fine way to live. She also manages to raise the ire of everyone around her with her actions, including breaking up peace talks and banishment from the only general store in the area. Katherine campaigns to have Meagan dead or removed from Sir's cabin. Meagan counters the moves while trying to preserve her Amish upbringing, not easy when Katherine is around. When bounty hunters shoot Sir, the girls have to stop arguments and tantrums to survive the gang of men wanting to kill them. With one girl able to shoot but refusing to kill, and the other girl willing to kill but having no idea how to shoot, they carry their respective outlooks into battle. But is the world ready when they stop fighting each other and team up to start fighting the world?
