Ana muses on how a writer can build page-turning tension.
Beats. The words that describe what the characters are doing with their hands, eyes, and feet during scenes with dialogue. Sentences that reveal what the POV character is thinking or feeling. Beats can up the tension by slowing down the action at critical moments. A hero being stalked by the villain can strain for the crack of a branch or creak of a staircase step.
Short sentences. "Who's out there?" sounds serious. We usually don't construct long or perfect sentences when we're under stress. We shout, ramble, blurt, repeat. We don't describe the pattern on the wallpaper.
Short (one line) paragraphs. Rapid fire dialogue conveys tension. Terse sentences make for a fast read, which helps the reader feel how the scene is building to a crescendo.
Deep POV (internal dialogue) reveals.
Plot (story arc).
