The silent invaders have come...to wage an invisible war for control of a backward, retrograde planet: Earth. Their plan is simple - to infiltrate human bodies, replacing the complex information stored in any human brain with new information - new responses...a new identity. Miles below the Nevada desert, a secret government research team rushed to develop a line of defense - a mechanical means of identity-switching, the most powerful form of mind-control ever conceived. Thus the stage is set for a bizarre interplanetary confrontation...its far-flung battles waged from a Las Vegas brothel to an enemy starship - not on land or in space - but deep in the very minds of men.
