Only a few scientists had even suspected its presence, and then, suddenly, it was there, dwarfing and threatening the Moon and wreaking havoc with Earth's tides and weather. The huge, garishly coloured artificial world has only stopped in the Solar system to refuel but its mere presence is a catastrophe for the inhabitants of Earth, who all struggle in their different ways to survive the climatic chaos it unleashes. A brilliant description of the of the days of chaos as total destruction threatens the Earth. Winner of the Hugo Award for best novel, 1965
