books that freaked me tf out

Hello!
Here are a handful of books that freaked me out, were gross, were scary, were unsettling, or scarred me in some way.
Thanks to ‪@frankiesshelf‬ for the idea in its entirety - Also just a great channel!
Sometimes a book freaks you out and it's not exactly a horror, sometimes a horror doesn't quite freak you out. These books freaked me out.
