I like a certain sort of horror, but I have a hard time describing it. I don't read very much horror though, but it's mostly because there's not a lot that I like.
Here are some I like:
Bad Girls Don't Die by Katie Alender. YA. First of all, the cover is dead amazing. It's what I fell in love with first. (Also, Katie Alender's blog is A+++) This is one of those horrors that isn't exactly scary...a little creepy sure. The MCs sister starts to change to the point where the MC starts to think something has possessed her. It's a really great read and has a sequel coming out!
The Demon's Lexicon & sequel The Demon's Covenent by Sarah Rees Brennan. YA. I would not call most paranormal YA horror, mostly because it isn't scary and doesn't even try to be. The Demon's Lexicon series is different. It's not going to make you turn on all the lights in your house or anything, but it is a story about magicians calling up demons for power and demons who very much want to enter our world by any means necessary. It is about a seriously troubled anti-hero.
Feed by Mira Grant. Zombies. Also, politics. I have described this book as a cross between Dawn of the Dead, Hackers, and The West Wing. It's kind of awesome, although also kind of scary. These zombies are not going to ask your prom. They are also not trapped on the other side of a fence. And they organize. But it's not ALL about the walking dead. It is also about a presidential race, and conspiracy theories, and bloggers who have become the real sources for news as they are some of the few willing to brave the zombie world for answers. Awesome!!!!
If you want something a little more adult and scary, I recommend The Walking Dead graphic novel series which has the bonus of being not just creepy, but also illustrated creepy. It is about zombies. It is about to debut as a tv show on Halloween.
Oh! And if you want to read something that is creepy, illustrated, and free, I highly, highly, highly recommend the online comic The Zombie Hunters. The illustrations just blow me away considering they are done by a girl in Canada for fun. The story is well thought out and well implemented and it can be both funny and really scary. http://www.thezombiehunters.com/index.php
