From the brilliant, bestselling author of Child 44 comes a suspenseful and fast-paced novel about an Antarctic colony of global apocalypse survivors seeking to reinvent civilization under the most extreme conditions imaginable. The world has fallen. Without warning, a mysterious and omnipotent force has claimed the planet for their own. There are no negotiations, no demands, no reasons given for their actions. All they have is a message: humanity has thirty days to reach the one place on Earth where they will be allowed to exist…Antarctica.
