The Hammer of God is vintage Clarke: superb storytelling, authentic science, and wonderful vignettes of life in the twenty-second century on Earth, the Moon, Mars - and in space. 'The Hammer of God', the short story on which this novel is based, first appeared in Time magazine in the autumn of 1992. It was only the second piece of fiction ever to appear in the magazine - the first having been Alexander Solzhenitsyn.
