In the world of Dimension X, the era of the automobile is dead. America is tied together by "Roadtowns"—massive, multi-lane conveyor belts traveling at 100 miles per hour, carrying the lifeblood of a nation.

But what happens when the men who move the world decide they should be the ones to rule it?

When a radical group of technicians sabotages the Sacramento sector, the roads don't just stop—they become a deathtrap of grinding steel and chaos. Chief Engineer Larry Gaines must dive into the thundering machinery beneath the surface to stop a madman from triggering a disaster that could kill millions.

The pulse of the nation is mechanical, and the rhythm is about to break. This is Dimension X.
