The local library's reading challenge

The local library is doing an "Exploring Horror Subgenres" challenge. The idea is to try out various different types of horror, read one from each category, maybe give something new a shot, etc. They have a list of recommended reading (you can also pick stuff for the challenge that isn't on their list, though).

Here's the library's recommended list (plus notes on what I've read):
( Cut for length )

For books not on the list, I'm planning on reading these two:

Slasher: My Heart is a Chainsaw by Stephen Graham Jones. I really enjoyed The Buffalo Hunter Hunter and have been meaning to read more of this guy's work.

Sci-Fi horror: Authority by Jeff VanderMeer. I've already read Annihilation, and enjoyed it enough to put the sequel on the to-read list, soooo I guess there's no time like the present. :V

Anyway! Has anyone read any of these? Thoughts etc? I find with a lot of horror the premise sounds interesting but the execution doesn't live up to my hopes. Which goes for movies too, I suppose.
