The Haunting of Hill House is a sprawling, 10-episode series filled with both existential and tangible scares, but the show wouldn't exist without its source material: Shirley Jackson's eponymous 1959 Gothic horror novel. Series writer and director Mike Flanagan adapted the book by taking the story's most important elements and applying them to a new plot that still feels familiar to Jackson's fans. While the novel and TV show are fantastic works of horror, the two Haunting of Hill House stories only share a few similarities.
Character names, themes, and a few passages from the book ended up in the series, but many of the scariest ghosts from The Haunting of Hill House TV show are Netflix inventions. If you enjoyed the series, you should read the novel because an entirely new and deeply terrifying adventure awaits.
