I am totally open to suggestion! For insight into my weird taste: I love Neil Gaiman, YA, nonfiction about adventures, Marcus Sedgwick, Rainbow Rowell, Stephen King, Harry Potter, Lauren Oliver, and Carson McCullers, and will take a chance on nearly anything that claims to be scary.
Lauren Beukes, maybe? I loved her first two books (science fiction in South Africa? Yes please more more more), but her two more recent are closer to horror than sci fi. The Shining Girls is a time traveling serial killer, and Broken Monsters is…. Ummm. I haven’t read it yet, but Detroit and creepy things.
I have a low tolerance for scary, but maybe check out this blog by the librarian who literally wrote the book on horror RA ;)
I’ve heard good things about Dare Me by Megan Abbott, but haven’t been brave enough to read myself. Psychological suspense with murder and cheerleaders.
