Following Rachel's father's disappearance during the war, her mother has been working as a live-in domestic for Ms. Moore, an orchid grower. As Rachel grows older, her mother starts to share stories about life before the National Border Defense System and how the people's rights were lost when the United States went to war with Korusal. Just a few days after the war started, the US created THE LINE, an invisible power source that separated the Unified States from what they now call Away. It is only when Rachel receives a mysterious message from beyond the border that she begins to learn about her country's true history and the parts her parents played during the War.
