Synopsis: From the back cover of the DAW first edition: "One would not have expected to find the last hideout of the ancient weird folk of legend and prehistory in an English forest of two centuries ago... and yet in that land which has always been haunted by the lore of little folk there had to be some truth behind such universal belief. The magic pen of Thomas Burnett Swann, master of fantasy and chronicler of the pre-humans, has produced in The Not-World one of his finest - and most piquant - novels. Here is the story of Dylan and Deirdre, of Thomas Chatterton... and of the balloon flight that brought them into an older and more enchanted land to mingle their fates with those of Arachne and the Night Mares in whom a rising industrial materialism could not longer believe."
