Danger in Paradise.

The first colonists to reach Tigris thought they had found Eden... but the planet had a horrifying effect on their children. Babies born there developed frightening telekinetic powers at the age of five. No one could control them -- and as the changelings grew and became aware of their abilities they initiated a bloodbath of chaos and violence that nearly destroyed the planet.

Two centuries after the Lost Generation, Tigrins have learned to cope with their strange planet and its effects. But a new threat is rising. In secret a medical researcher is experimenting with the TK ability. His guinea pigs are stolen children; his object, to extend their powers past adolescence and into adulthood. If he succeeds, Tigris faces disintegration.
