Man, this is one of those books where summarizing by chapter feels almost beside the point. You get pulled into the slow, icy dread of the Overlook, and breaking it down into pieces can miss the suffocating whole of it.
That said, the structure is pretty deliberate. The early chapters in Boulder are all about the fragile hope of the Torrance family, especially Danny's psychic 'shining' sensing the coming horror. Once they're snowed in, the chapters become these tightening coils of isolation—Jack's growing madness fueled by the hotel's ghosts, Wendy's desperation, and Danny's terrifying visions. It's not a series of jump-scares; it's the boiler pressure climbing, page by page.
Specific moments that wrecked me: the wasp nest chapter, which is this perfect metaphor for dormant evil, and the party in the ballroom where the past literally comes alive. The chapter with the topiary animals moving still haunts my walks in snowy parks.
