The Sleep Eaters is the story of the first victim of a mental invasion force that is now hovering over our world. He finds himself in the grip of mental processes from beyond the Earth, in which he learns of the coming physical invasion by a race
far out in space. Before this can happen the Earth is to be cleared of Man. The unwilling watcher finds that this will be done, not by an outer force, but by employing Man's own genius for self-destruction.

In this story of how he tries to make his warning penetrate, his persecution and pursuit are as tense and exciting as any thriller, and his vision of Man's mind being slowly eroded by the Sleep Eaters and pursuing its own course to destruction is startling, fascinating and horrible. And it could be happening now.
