October Art Series & Thriller Book Suggestions?

Spooky Scary...

I love horror. Books, movies, TV shows, you name it, and I devour it. But as I am particularly fond of reading (and do so on my commute to and from work daily), I would LOVE some of your book suggestions of your favorite horror/thriller novels! I'd love to give them a read.
Lately, I've read The Winter People and that was amazing (I'll be reading everything by that author), and Girl In Snow was also really good. Apparently there's something about winter?

Anyway, if you have any good book recommendations, let me know! (And I will continue to let you know when I've read a good one, too!)
