The Silkie -- A living spaceship, impervious to heat and cold, virtually indestructible and capable of travelling at supersonic speeds. The Silkie -- Similar to a human being, but not the same.

The Silkie -- A friend of Earth, or a pitiless, alien destroyer?

Therefore Doona could be colonized only if an official survey established that the planet was both habitable and uninhabited. But Spacedep had made a mistake -- Doona was inhabited. Now the colonists choice was limited. Leave Doona and return to the teeming hell of an overpopulated Terra. Or kill the catlike Hrrubans. Or learn, for the first time in history, how to coexist with an alien race...
