Spores

Secrets aren’t the only things that won’t stay buried.

When an earthquake strikes downtown Denver, far from the nearest active fault system, the USGS dispatches Dr. Dayna Raines and an emergency response team to investigate. They discover that the epicenter corresponds to a decommissioned deep injection well once used by the U.S. Army to dispose of chemical weapons, which have eroded the earth and created the unstable cavern system responsible for the seismic activity.

Their mission is to descend into the unknown depths, evaluate the fault zone, and initiate a controlled demolition of the subterranean cavity before another earthquake strikes, causing a mass casualty event. And they’re running out of time.

But military scientists had been experimenting with even deadlier armaments, including a biological organism so lethal that they were forced to bury it two miles down, where no one would ever find it.

Until now.
