When an asteroid disintegrated on entering the Earth''s atmosphere, some pieces fell to earth. Billy and his friend had been watching through their telescope in the early hours as a small meteorite ploughed into the fields behind their Oxfordshire home. The boys retrieved the meteorite and took it home before the authorities had time to search the area. What the boys found while examining the rock was to change the world. Previously humans had been the dominant species on Earth, now they had found a challenger.
