The Haunting of Hill House by Shirley Jackson

Thanks for voting! Here is the description: Four seekers have arrived at the rambling old pile known as Hill House: Dr. Montague, an occult scholar looking for solid evidence of psychic phenomena; Theodora, his lovely and lighthearted assistant; Luke, the adventurous future inheritor of the estate; and Eleanor, a friendless, fragile young woman with a dark past. As they begin to cope with chilling, even horrifying occurrences beyond their control or understanding, they cannot possibly know what lies ahead. For Hill House is gathering its powers—and soon it will choose one of them to make its own.
