It began with the sound of a beating heart ... four thousand feet below the surface of the earth. Something was living down there, in a strange void that refused to respond to science's probings: an impossible life living in an impossible place.
An impossible life that had known birth in a time before Earth's fiery surfaces had cooled!
And now that life was awakening, stirring under the probe of men who were unable to refrain from questioning the unexplained ... stirring, and preparing to come forth from its ages-old resting place.
Men wanted to believe that the creature would be friendly ... but it came from a world that existed before men were created.
How could it find kinship with such totally strange creatures ... and would it even be able to recognize that men were intelligent, rational beings?
