Sarah Whitmore is buried alive in a punishment room that doesn't exist on any map, sentenced to forty years of daily naked inspections and forced running under the watch of men who despise her. But as she learns the brutal rhythms of her captivity, she discovers that the cracks in the system are not flaws—they are her only weapons. The question is not whether she can survive, but what she will become when she stops simply enduring and starts fighting back.
