“They say it's going to get worse. That it's not going to end." The snow won't stop falling in this dangerous-new-world. The long, bitter winters are getting worse, and a state of emergency has been declared across Europe. In Poland, the villagers are subject to frequent power cuts and fuel shortages. After the death of her grandmother and the evacuation of her village, fifteen-year-old Magda joins forces with the arrogant, handsome Ivan and smuggles her way onto a truck bound for London - where she hopes to find her mother. But London, when they reach it, is a nightmarish world, far from welcoming. Riots are commonplace and the growing chaos is exploited by criminals and terrorists alike. Magda's mother is not to be found, and as the lost girl struggles to come to terms with her changing situation, she eventually becomes friends with a rag-tag group of travellers planning a new home and future. They will need all the cunning and know-how they possess as they realise that the frozen wilderness of Britain has become just as lawless as the as the city.

Fifteen-year-old Willo was out hunting when the trucks came and took his family away. Left alone in the snow, Willo becomes determined to find and rescue his family, and he knows just who to talk with to learn where they are. He plans to head across the mountains and make Farmer Geraint tell him where his family has gone. But on the way across the mountain, he finds Mary, a refugee from the city, whose father is lost and who is starving to death. The smart thing to do would be to leave her alone—he doesn't have enough supplies for two or the time to take care of a girl—but Willo just can't do it. However, with the world trapped in an ice age, the odds of them surviving on their own are not good. And even if he does manage to keep Mary safe, what about finding his family?.
