The spookiest day of the year is tomorrow. In celebration, here are a handful of books that might be so frightening and scary that you won’t want to turn off the lights…

Check out Flavorwire’s The 50 Scariest Books of All Time to see what met their spooky requirements. Stephen King’s It makes the list, as well as classics like The Exorcist. Some of the titles may surprise you, like Margaret Atwood’s The Handmaid’s Tale and William Golding’s The Lord of the Flies. One of my personal favorites on the list is House of Leaves by Mark Z. Danielewski. It is a chilling tale about a blind man who dictates a story about a house with the ability to grow, and keep growing. Are you brave enough to read any on the list?

If you are a fan of young adult fiction but still want to read a horror novel that will give you goosebumbs, check out Snappy Pixel’s 22 of the Best Young Adult Horror Books to Read for Halloween. Some of the novels, like Miss Peregrine’s Home for Peculiar Children by Ransom Riggs, are simply creepy. Others, though, like Rabbits in the Garden by Jessica McHugh and Bad Girls Don’t Die by Katie Alender, really pack the spook factor. Just reading the summaries put me on edge.

If you’re in need for a scary story right this second, check out this list from Blastr of 25 short stories that are currently online now. Stories from both Stephen King and H.P. Lovecraft are available as well as stories from more classic authors like Arthur Conan Doyle and Edgar Allan Poe. If you’re skipping the parties this year, these stories will be just the thing to put you in the Halloween spirit.
