Under the Dome is a 2009 science fiction novel by American author Stephen King. It is the 58th book published by King, and it is his 48th novel. The novel focuses on a small Maine town, and tells an intricate, multi-character, alternating perspective story of how the town's inhabitants contend with the calamity of being suddenly cut off from the outside world by an impassable, invisible glass dome-like barrier that seemingly falls out of the sky, transforming the community into a domed city.
