Emma, Norman and Ray are the brightest kids at the Grace Field House orphanage. And under the care of the woman they refer to as "Mom," all the kids have enjoyed a comfortable life. Good food, clean clothes and the perfect environment to learn - what more could an orphan ask for? One day, though, Emma and Norman uncover the dark truth of the outside world they are forbidden from seeing.

Fifteen children escape Grace Field House, a false paradise, hoping for a chance at freedom. Instead, they encounter plants and animals they have never before seen, and are chased by demons. The outside world is so beautiful, and yet is almost too cruel to face.

Even so, the children refuse to give up. They are guided in their search for better lives only by a message from Minerva and a pen Norman left behind in order to fulfill their promise to return to the House to save those of their family who are still trapped within.
