Narrative Stylistics is the most recently established idea and area in contemporary stylistics. William Labov (1972), Fowler (1977, 1996) and Bakhtin (1986) were major contributions to contemporary stylistics and narratology. Without a doubt, the story has gained a bigger place in the minds of stylists, analysts, and critics. The social, historical, and cultural foundations of story stylistics are the most important, where narrative and discourse stylistics collide. It gave the best scope to study Amitav Ghosh's historical fiction in Sea of Poppies and River of Smoke with narrative and cognitive stylistics. This paper focused on the study of narrative stylistics and deictic shift theory, and how they were employed in these two novels that resulted in the cognitive effect on readers' minds.
