This is a reread for me. I loved the book the first time I read, and I'm savoring the reread. Shirley Jackson's writing style is so satisfying to me - terse yet still somehow so evocative.
The first paragraph of this book has one of the best openers I've ever read:
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 neatly, 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.
I'm reading this one for Classic Horror, which was the first call of the game!
