Read the following excerpt from an analytical essay on the evolution of narrative techniques in modern literature:
"In contemporary fiction, authors increasingly employ non-linear storytelling to enhance the complexity of their narratives. This approach not only reflects the fragmented nature of modern life but also challenges traditional chronological narratives. For instance, in works such as David Mitchell's 'Cloud Atlas', the intertwining of separate yet connected stories across different time periods illuminates how individual actions resonate through time. Alternatively, authors like Jennifer Egan utilize techniques like PowerPoint presentations in 'A Visit from the Goon Squad' to disrupt readers' expectations and provoke deeper engagement. Such structures prompt readers to piece together narratives in a way reminiscent of assembling a puzzle, making the reading experience uniquely interactive. As these techniques gain traction, they invite readers to reconsider how stories are told and what constitutes narrative coherence."
