Under the Dome is a science fiction novel written by Stephen King, first published in 2009 by Scribner. Spanning over a thousand pages, it depicts the sudden isolation of the fictional small town of Chester's Mill, Maine, when an invisible, indestructible dome descends from the sky, sealing off the residents from the outside world. As resources dwindle and tensions escalate, the story explores the breakdown of society, power struggles, and human nature under extreme pressure, drawing parallels to King's earlier works like The Stand but with a localized, claustrophobic focus.
The novel features a large ensemble cast, including local politicians, a radio station owner, a veterinarian, and a methamphetamine dealer turned antagonist, whose interactions reveal themes of corruption, survival, and redemption. King's meticulous world-building captures the minutiae of small-town life amid escalating crises like food shortages, toxic air, and internal conflicts. Widely acclaimed for its gripping narrative and social commentary, it became a bestseller and solidified King's reputation for epic, character-driven tales of apocalypse.
