From back cover of Pocket Books paperback, June 1980:

In a world now ravaged by drought and famine.

Jean Brighton and Arthur Cluny grew up in the limelight, children of space pioneers who built the orbiting space laboratory. Now Arthur carried on his father's work at the lab. But Jean fled into isolation, harboring a hatred for the space station and the intrigue that surrounded it.

How could she know that in her desert solitude she would hold the key to the future of the space station she so desperately wanted to forget... that for a moment international peace would rest in her hands... or that Arthur would come to wrest from her a secret she would rather not face, a secret that could return the world to... JUNIPER TIME?
