There’s just something about horror that makes it better in small doses. You can only ratchet up the tension so many times before people start getting wise to the game you’re playing. The scares get stale, and then your book is about as frightening as an elementary school haunted house. I don’t say that to rag on authors who write long-form horror pieces. Stephen King’s IT is one of my favorite books of all time — as well as one of the scariest books I’ve ever read — and it’s over 1,000 pages. Tananarive Due’s The Good House clocks in right at the 500-page mark, and Mark Z. Danielewski’s House of Leaves is 700 pages long and still feels bigger on the inside — which, I guess, is probably the point.
