Remembered that I've had Hill House downloaded on my Kindle a long time already so I've started reading it too. I generally avoid horror these days but it's been on my radar a long time, and we're close

No live organism can continue for long to exist sanely under conditions of absolute reality; even larks and katydids are supposed, by some, to dream. Hill House, not sane, stood by itself against its hills, holding darkness within; it had stood so for eighty years and might stand for eighty more. Within, walls continued upright, bricks met nearly, floors were firm, and doors were sensibly shut; silence lay steadily against the wood and stone of Hill House, and whatever walked there, walked alone.
The opening paragraph is indeed somewhat famous, even Stephen King has praised it, and it's easy to see the ways it influenced The Shining. (Apparently part of the opening is directly used in the Dark Tower books as well.)
