As the 21st century draws to a close a growing group of rebels plot to declare the human planets independant from the Milieu and end a thirty-year association. They are helped by the insane Fury who seeks to rule the galaxy itself.

A key figure in Fury's scheme is Dorothea MacDonald. Possessed of extraordinary metapsychic powers she wants only a quiet life and hides away on the planet Caledonia, She rejects Fury's overtures and the monster vows to destroy her.

When the Milieu, too, discovers her powers she is forced to leave her family and use her powers for the benefit of all. At the Metappsychic Institute she discovers that one day she will rule Caladonia and meets Jack the Bodiless realizing that his mind is the only one that approaches hers in its power. Together they offer the only hope of defeating the rebels.

And all the while Fury plots to kill them both and seize the Milieu for itself . . .
