A Bone-Chilling List of the 19 Best Horror Books

Unseen foes are terrifying enough, but what about ones you can't look at? That's the concept of "Bird Box" ($9), the horror book by Josh Malerman, which was later turned into a Netflix film.

Malorie has to lead her children to safety in a world filled with monsters that, if seen, drive a human to commit suicide. Their escape route is 20 miles down a river, blindfolded the entire time. If you loved the film, you'll love going deeper into these characters' stories in the book.
