Under the Dome by Stephen King

Under the Dome is classic Stephen King--long and suspenseful. An invisible barrier suddenly descends on the small town of Chester's Mill, cutting it off from the rest of the world. How the townspeople react to their enforced isolation and dwindling supplies is the heart of the novel. There are a lot of characters, and they are a little too neatly divided into "good" and "evil," but these are minor quibbles. The ending is a disappointment, but the build-up is worth the read. It's a page turner.
