Any really scary books written by women?

I'm looking for terrifying or disturbing horror books written by female authors. I know 'scary' is subjective, so I'll try to be specific about what I want.

I prefer supernatural horror, especially if it's something unique. I love cosmic horror. I enjoy narratives centered around young characters. I'm not at all interested in serial killers or "humans are the real monsters" type stories.

Off the top of my head, these are some books that have scared the hell out of me:

It, by Stephen King

Threshold, by Caitlin R. Kiernan

House of Leaves, by Mark Z. Danielewski

The Twisted Ones, by T. Kingfisher

And for good measure, some of my favorite horror movies:

Skinamarink

It Follows

Hereditary

The Babadook

Let the Right One In

The Witch

I Saw the TV Glow
