The Oxford Bookworms Library provides superb reading and student / teacher support for the classroom, and is also highly recommended for schools running Extensive Reading Programmes, offering the right range of books that encourage students to read for pleasure. On the Polar ice-cap, 640 kilometres north of the Arctic Circle, the deadly, icy winds can freeze a man to death in minutes. But the survivors of the crashed airliner are lucky — they are rescued by three scientists from a nearby weather station. But why did the airliner crash in the first place? Who smashed the radio to pieces? And why does the dead pilot have a bullet hole in his back? The rescue quickly turns into a nightmare: a race through the endless Arctic night, a race against time, cold, hunger — and a killer with a gun.
