The Haunting of Hill House by Shirley Jackson

Trade paperback format.  Introduction by Laura Miller.  Highly recommended!  This is the lovely Penguin Classics Deluxe edition.

The greatest haunted house story ever written, the inspiration for a 10-part Netflix series directed by Mike Flanagan and starring Michiel Huisman, Carla Gugino, and Timothy Hutton
 
First published in 1959, Shirley Jackson’s The Haunting of Hill House has been hailed as a perfect work of unnerving terror.

It is the story of four seekers who arrive at a notoriously unfriendly pile called Hill House: Dr. Montague, an occult scholar looking for solid evidence of a “haunting”; Theodora, his lighthearted assistant; Eleanor, a friendless, fragile young woman well acquainted with poltergeists; and Luke, the future heir of Hill House.

At first, their stay seems destined to be merely a spooky encounter with inexplicable phenomena. But Hill House is gathering its powers—and soon it will choose one of them to make its own.
