Things could hardly be better for the Grace Field House orphans! Despite the fact that they have no parents, they form a large, happy family with the other children and a caring "Mama," and no child is ever forgotten since they are all adopted by the age of 12. Despite the fact that their daily lives are filled with severe examinations, children are allowed to play outside. There is just one rule they must follow: they must not leave the facility. Emma and Norman, two of the highest-scoring orphans, stray outside the fence one day and learn the horrible reality about their existence: they are all cattle, and their orphanage is a farm where a secret race of demons cultivate food. There are only a few months left in the year.
