SCIENCE DISCOVERED IT.
Tiny implants in the brain that enhanced intelligence and established mind-to-mind links between species that had previously been isolated and mute. Dogs, monkeys and man could communicate. Animals, and even severely retarded humans, could be taught complex tasks. Jonathan was the first human subject.INTERTEL SEIZED IT.
The giant consortium that had funded the research presented the discovery as a boon for mankind … and secretly planned to use it to rule the world.
JONATHAN AND HIS FRIENDS USED IT. With the mind-enhancing power that made them think and act as one, they rebelled and looked upward—toward the stars!
