Two Indiana teenagers start off on a warm spring day on a simple hike and wind up initiating a series of events that threaten to destroy the North American continent. Matt and Jason Purkheiser become trapped in a strange, underground structure that changes within three days from a sanctuary to an instrument of global destruction. This fast-paced, action adventure uses the setting of a small, quiet Indiana town to probe the possibility of ancient and alien terraforming. Three hundred million years ago, there was only one continent. Is there another explanation for the five continents of today other than natural continental drift?
