Just down Route 119 in Chester’s Mill, Maine, all hell is about to break loose. . . .

On an entirely normal, beautiful fall day, a small town is suddenly and inexplicably sealed off from the rest of the world by an invisible force field. Planes crash into it and rain down flaming wreckage. A gardener’s hand is severed as the dome descends. Cars explode on impact. Families are separated and panic mounts. No one can fathom what the barrier is, where it came from, and when—or if—it will go away. Now a few intrepid citizens, led by an Iraq vet turned short-order cook, face down a ruthless politician dead set on seizing the reins of power under the dome. But their main adversary is the dome itself. Because time isn’t just running short. It’s running out.
