Identity Matrix — Jack L. Chalker

THE INVADERS ARE AMONG US

THE MILWAUKEE JOURNAL:
"While backpacking in Alaska, Victor Gonser, a 35-year-old Ph.D. in political science, finds himself trapped in the body of a 13-year-old Tlingit Indian girl. A little later he is forced from there into the spectacularly beautiful body of an 18-year-old blonde. He finds that the switches are part of a skirmish for Earth by two alien races.... And that is just the beginning. Like many of Jack Chalker's earlier books, this one is almost totally unpredictable and will keep you guessing to the last page."

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 matrix!

Miles below the Nevada desert, a secret government team rushes 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 wages from a Las Vegas brothel to an enemy starship--not on land or in space--but deep in the very minds of men.
