Out of the Earth

Something else has been living beneath the Earth. Now, it's their time to rule . . .  The Yellowstone supervolcano has begun to erupt, sending North America into chaos and the rest of the world into a panic. People are dangerous and desperate, knowing this will plunge the continent, and the world, into perpetual winter. Until they realize that the eruption is the least of their worries . . .  Out of the massive chasm comes more than ash and lava. Giant monsters emerge, bent on destroying everything in sight. Federal Marshal Lu Morgan and a ragtag group of survivors and soldiers must fight hard to stay alive and beat back the invasion of massive creatures. It is a race against time, and a race for survival, as all involved struggle to find answers as to where the monsters came from and how to stop them.
