Make it yours

Three ways to take this prompt somewhere nobody else will.

  1. Never fully show the thing. Describe what it leaves behind.
  2. Make the hero's worst fear about themselves come true, not just the monster.
  3. Use a single repeated sound as the warning sign.

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.
