10,000 days ago, Comet 23 struck the Pacific Ocean with the magnitude of all the nuclear weapons in the world. The Beck family was among the lucky few who survived the heat blast and firestorms. And then the freezing began. The comet knocked the Earth away from the sun, encasing the planet in snow and ice. For those who survived, life is violent and dangerous. The daily battle isn’t just against the punishing climate but against each other for the basic necessities that mean life or death. Still, the weather is growing colder and the ice is expanding. Villages are being crushed by violent tremors. And then the Becks find an object from the past, buried deep in the ice. And with it comes a choice – a choice that can either save them or destroy them.
