The Mara Dyer Trilogy - Michelle Hodkin
The whole series is weird, wild, and just all around one crazy trip. I don't want to spoil anything (and just my luck I would) so I'll just tell you to read these books and leave it at that!
The Peculiar Children Series - Ransom Riggs
Words can't describe how much I love this book. It has monsters crawling out of the woodwork, and it's creepy as hell. Read them all - you won't be disappointed.
Survive the Night - Danielle Vega
Murder, underground subway parties, a friend gone crazy - this book has it all.
Asylum - Madeleine Roux
Kids staying at a college dorm that was originally an asylum! How can you not love that?!
The Dead Girls of Hysteria Hall - Katie Alender
Death and ghosts and a girl who doesn't know she's dead - this whole book is just amazing!
The Harry Potter Series - J.K. Rowling
I know these aren't technically creepy horror novel type reads, but there is enough of a creepy, scary aspect in each book to make them worthy of being read in October (or really any time of the year!)
Every Heart a Doorway and Down Among the Sticks and Bones - Seanan McGuire
These can both be read as standalones, but you should read Every Heart a Doorway first. Both books have some murder, lots of darkness, and twin sisters that will kind of make you sit up and say "What?!"
