A million years ago a powerful alien species lived a dead planet into the narrow life-supporting zone of an old, cold class MD star. Then it gave he world an atrmosphere settled its surface with a bizarre mixture or creatures- some long since vanished from Earth-erected marvelous hivelike cities, and disappeared.
But Humanity's arrival had apparently set the planet's hidden machinery to working. The dead cities had begun to glow at night and even the animal were undergoing startling trasformations.
So Dorthy Yoshida, astronomer and reluctanmt telepatn, was summoned from self-imposed exile near distant Earth and set to search tfor the mind that moved the world.
i had read many excellent short stories by this author, and was genuinely looking forward to this one, his first novel. the title alone promised grand and sweeping space adventure. but all the action takes place on a single planet which may or may not be a crucial locus of what may or may not be an interstellar conflict.
not much about the underlying plot was ever made clear, and the characters are shallow, at best.
by the time i finally reached the end, i was bored and disappointed.
