"After the first human contact with the Siwannese, that entire race committed mass suicide.
So the terran government made a law -- no further contact would be allowed with sentient creatures anywhere in the galaxy.
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 . . . "

First volume of the Harper Hall trilogy, part of McCaffrey's Pern universe.
"Every 200 years or so, shimmering threads fall, raining black ruin on Pern. The great dragons of Pern hurl themselves through the beleaguered skies, flaming tongues of fires to destroy deadly Thread and save the planet. It was not Threadfall that made Menolly unhappy. It was her father who betrayed her ambition to be a Harper, who thwarted her love of music. Menolly had no choice but to run away. She came upon a group of fire lizards, wild relatives of the fire-breathing dragons. Her music swirled about them; she taught nine to sing, suddenly Menolly was no longer alone."

This is a collection of short stories that introduce Helva (XH-834), the to-be-legendary Ship who Sang. Helva was born physically defective, but with a perfectly good brain. Mankind of McCaffrey's Central Worlds universe has learned to save these children and allow them to live productive lives -- as the encapsulated 'brain' running a spaceship......or space station, or city. McCaffrey masterfully paints the growth of Helva as a human being, both limited and freed by the titanium shell she is encased within.
An excellent introduction to science fiction, McCaffrey has more recently authorized several 'sequels' involving shell-persons and set in the same universe: "The Ship Who Searched," "Partnership," and "The City Who Fought."
