On a beautiful fall day in Chester's Mill, Maine, the town in inexplicably and suddenly sealed off from the rest of the world by an invisible force field. No one can fathom what this barrier is and when - or if - it will go away. Dale Barbara, Iraq vet and now a short-order cook, finds himself teamed with a few intrepid citizens. Against them stands Big Jim Rennie, a politician who will stop at nothing - even murder - to hold the reins of power, and his son, who is keeping a horrible secret in a dark pantry. But their main adversary is the Dome itself.
