When the Order of Planetary Engineers sent Hall Davenant to Ganymede for a terraforming survey, they knew that the job on the airless, frigid Jovian moon would be tough. Changing it to resemble Earth - with fertile land, water and good air - was the biggest and most important planet conversion job ever attempted by the Engineers. But they hadn't counted on the already too Earthlike behaviour of the Ganymede colonists, who had never altered the ancient Earth-born habits of intrigue, bigotry and double-dyed treachery!
