Earthsound

Your name is Harry Vail and you alone know the terrifying truth—or do you?

You are an expert on earthquakes and you fear their awesome power to the point of insanity. Now you are sure that an earthquake is building below your very feet. Your house, your family, your friends, your town, are about to be destroyed.

The cracks appearing in the walls; the "accidental" deaths of local people; the strange movements of inanimate objects; all increase the certainty of your belief and the urgency of your warnings to those around you. The trouble is, there are others who have another, even more frightening explanation for what is happening; and God help you all if they are right.
