Authors use structure by strategically placing cliffhangers at the end of chapters, creating a sense of anticipation and mystery for the readers. They also may employ nonlinear storytelling to reveal information in a suspenseful way. Pacing is another crucial element, as authors can build tension by gradually increasing the speed of the narrative during intense scenes and slowing down during moments of reflection or revelation. By controlling the flow of information and events, authors can keep readers on the edge of their seats, eagerly turning pages to uncover what happens next.
