" Washburn brings a new kind of terror."-Marc Cameron

FIRST THE GROUND SHAKES . . .
At Yellowstone National Park, earthquake tremors are common. But today, park scientist Tucker Mayfield detects something different- a disturbing new increase in activity-and intensity . . .

THEN THE LAVA RISES . . .
Lurking beneath the park's natural wonders, earth's largest supervolcano begins to awaken after 640,000 years. If-or when-it blows, two-thirds of the North American continent will be destroyed . . .

NOW THE WHOLE WORLD TREMBLES . . . IN FEAR
Racing against time, Tucker Mayfield mobilizes a team to evacuate all visitors from the park-including his family at the Old Faithful Inn. But when the earthquakes intensify, and the death toll rises, a shockwave of panic spreads across the nation. Troops are deployed, emergency plans activated. But nothing can stop a natural disaster of this magnitude. When the volcano erupts, doomsday begins-and no one gets out alive . . .
