Recommendation for an entertaining horror/thriller

I've been reading a lot of heavier old/ancient literature (The Iliad by Homer, and before that The Grapes of Wrath by Steinbeck), and frankly I feel like I just need something entertaining. Something not necessarily light, but a horror or thriller that kept you up at night thinking about it, wanting to just get one mord chapter in before setting it down.

What would you guys suggest?
