Writing horror books

Something is wrong here, and it's getting closer.

Horror is defined by the feeling it creates: dread, then fear, then the urge to keep reading anyway. The threat might be a ghost, a creature or the person in the next room. Underneath, the best horror is about something real: grief, guilt, the things we can't control.

What readers expect

  • Dread that builds
  • A threat that can't be reasoned with
  • Characters out of their depth
  • An ending that doesn't let you off easy

A tip before you start

What you don't show is scarier than what you do. Let the reader's imagination fill in the dark.
