It starts with the dogs. They won't stop barking... And then the earth shrugs—8.9 on the Richter scale in the world's biggest earthquake since 1755. It hits New Madrid, Missouri, a sleepy town on the Mississippi. Seismologists had predicted the disaster . . . but no one listened. Within minutes, there is nothing but chaos and ruin as America's heartland falls into the nightmare known as the Rift—a fault line in the earth that wrenchingly exposes the fractures in American society itself. As a strange white mist smelling of sulfur rises from the crevassed ground, the real terror begins for the survivors, including a teenager separated from his mother, an African-American engineer searching for his daughter, a TV preacher whose visions of hell have become all too real, and a sheriff cum Ku Klux Klansman who seeks racial vengeance in the midst of disaster. It can happen. And sooner or later, it will.
