You may have heard of a writer named Stephen King. He wrote a few books that are kind of scary? Yeah? With more than 50 books in print, King is insanely prolific. From classic works of horror like Carrie and The Shining to enormous historical / science fiction books like 11/22/63, King's fans never have to wait too long for his next novel. It seems like the wheels in that amazing (amazingly terrifying?) mind are always turning!

King obviously has a way with words, and his Twitter is no exception. Full of hilarious thoughts and weekly answers to reader questions, it's always entertaining. He alternates between adorable tweets featuring his dog, Molly (aka The Thing of Evil), and recommending the books he's reading. Being the master of horror that he is, I consider him an authority on recommendations in that genre. You could make an entire reading list based on Stephen King recommendations, and be set for a long time.

Here are 11 books that scared the unshakable Stephen King, and so are pretty much guaranteed to keep you up at night and/or give you nightmares. But hey, that's the fun part!

A Head Full of Ghosts By Paul Tremblay

After 14-year-old Marjorie Barrett starts acting strangely, her parents are devastated to find out that she is showing signs of acute schizophrenia. But when doctors are unable to help Marjorie, the Barrett home turns into a house of horrors, and the family turns to the Catholic church, which suspects demonic possession. The family's plight is made into a reality TV series, of course, and things only go downhill from there. Fast-forward 15 years, and Marjorie's younger sister is interviewed about the terrifying past, opening old wounds and psychological horror.

What Stephen King Says: "Scared the living hell out of me, and I'm pretty hard to scare."

What unfolds is a mystery of suspense, betrayal, and (of course) murder.

What Stephen King Says: "Terrific crime/suspense/mystery novel, but the real revelation is his fresh and original voice."
