If you haven't guessed, I'm a huge horror buff and I can't get enough of the stuff, much to the joy and irritation of my boyfriend.
The horror themed website Horror Novel Reviews has compiled a list of their top 100 scariest horror novels and I'm pleased at some of the titles on the list, especially Penpal by Daniel Auerbach. I haven't read the full novel but I've read his reddit posts and they're genuinely unnerving to read. The Stepford Wives made the list as well, much to my joy. Granted our society isn't at the level where we could replace people with lifelike robots, but the horrifying thing is that I can still imagine that a good many would willingly ship their spouses (male and female both) off to a factory to get "upgraded".
I'm also pleased that it doesn't fall predominantly in any one direction. Granted there are more recent books than old-old ones, but they aren't going for any one specific theme or direction. If you're looking for something to read this summer like I am, this is a good place to start.
