Sixteen-year-old Raven is doing community service as a camp counselor in the Canadian wilderness in an effort to repair the damage she's done to her life, but all her good intentions go up in smoke when the Nahx invade. They destroy cities and take control of the planet with terrifying swiftness. In their remote camp in the foothills of Alberta, Raven and her friends try to remain undetected, and find a way to survive the winter. Raven and Eighth, one of the Nahx, cross paths as autumn turns to winter. They should hate each other, but maybe they can help each other. Raven and Eighth must warily forge ahead together in a search, not just for safety, but also for answers.
