Authors use narrative structure to manipulate the reader's perception of time and events by controlling the pacing, order, and focus of the story. By shifting between different timelines, including flashbacks or flash-forwards, authors can create suspense, reveal information gradually, or provide deeper insights into characters' motivations. Additionally, using techniques like foreshadowing, unreliable narrators, or nonlinear storytelling can all contribute to shaping the reader's understanding of the events and the passage of time within the narrative. Ultimately, these narrative choices influence how readers interpret the sequence of events and the characters' development, leading to a more engaging and immersive reading experience.
