answer:Misery and The Shining, both by Stephen King. They’re the only ones I’ve read, both terrifying – much worse than the movie adaptations. I never thought a book could be scarier than a movie, especially ones as tense as Misery/The Shining, but the books had me sat on the edge of my seat, biting my nails and shrieking like a freak at the scary parts. I’ve heard that any Stephen King book is a good read, though. I’d love to read more. But for the moment I’d definitely recommend those two.
