The creatures of dreams come alive int he world Zenna Henderson...These are some of them: The Grunder, a thing of horror which if defeated restores love...The Noise-Eater, created by a child out of his fevered imagination, gobbles up anything, or anyone, which makes a sound...The Coveti, residents of an alien world poisoned by the intrusion of the stranger from Earth..and The Beast Hill, an ordinary mound of earth, except that its grass resembles fur, and doesn't it move?
