​In the shadow of a restless earth, America's Pacific Northwest trembles as Mount St. Helens unleashes a cataclysmic eruption, without warning. Ash, fire and fury rain from the sky choking cities, burying highways and crippling the country.

 

But St. Helens is only the beginning.

 

Across the Pacific, a greater terror stirs. Mount Fuji, Japan’s sacred giant rumbles toward a VEI 6 eruption. Graham Mercer, a nuclear scientist at the Hamaoka Nuclear Power Plant, fights to avert a meltdown as seismic shocks cripple the grid and spent fuel pools teeter on the edge of catastrophe. If the cooling systems fail radioactive waste will poison the globe.  

 

As the Ring of Fire awakens the world must confront a terrifying reality -  this isn’t just one eruption - it’s a seismic reckoning and no corner of the world is safe.
