On a beautiful autumn day, a small New England 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 rag 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.
