An epic science fiction thriller by Stephen King. The story is set in the quiet town of Chester's Mill, Maine, where life changes in an instant when an invisible, impenetrable dome suddenly seals the town off from the outside world. Planes crash into it, vehicles collide with it, and no one can enter or leave.

As food, fuel, medicine, and hope begin to run out, the town descends into chaos. While ordinary citizens struggle to survive, corrupt local politician James 'Big Jim' Rennie seizes the opportunity to tighten his grip on power, manipulating fear and violence for his own gain. Meanwhile, former Army captain Dale "Barbie" Barbara emerges as one of the few people willing to challenge the growing tyranny and uncover the mystery behind the dome.

Blending science fiction, horror, political intrigue, and psychological drama, Under the Dome explores how ordinary people behave under extreme pressure. It is one of Stephen King's most ambitious novels, combining a large cast of memorable characters with suspense, social commentary, and a compelling central mystery.
