It's not so much that Molly's concerned about relocating to inside a spherical construct the diameter of an entire solar system, but the fact that she also has to live alongside members of the same alien species that murdered her family. And when the Servants of the Abiding Truth—a violent ex-Covenant sect under the guidance of the notorious Pale Blade—somehow makes its way inside this supposedly impregnable sphere, Molly is now forced to consider if she and her new parents have made a terrible and fatal mistake in coming here....
