I've read A Kiss Before Dying and The Stepford Wives, but I don't know if I would classify them as horror. Rosemary's Baby is horror (or so I'm assuming, because I haven't actually read the book or seen the movie, though I know the basic plot), and I'm pretty sure I have it on my TBR pile.
I've read Swan Song, and enjoyed it but I kept comparing it to The Stand (and it is so similar in terms of plot). I have Carrion Comfort on my TBR pile, and I've heard of The Terror. I may give the former a read this month.
Yeah, they do. They are quite short books as well, with not much empty filler.
