Agar grows up in a community of Anabaptist conscientious objectors who have fled from Earth to another planet, barely habitable, where they live in hardship. They watch the Earth from afar expecting to find that the rest of humanity has destroyed itself. After Agar's sister Temar gets a job in the command center, the mysterious Castle, Agar begins to realize the price of the community's choices.
