The explosions come in the night. Miranda1, Mannfred, Grannie, and the one thousand children of Oculum must flee their farm, chased by the UnRuly. But there is hope: an old friend sends word of a book that may hold the secret to their survival. Just as they begin their journey through the wasteland, Echo1 wakes from an eighty-three-year sleep and is given a mission to find the four domes of the children of Oculum, and to find the First One, whatever the cost.
