Khaled Hosseini, an Afghan diaspora author with several notable works, is best known for his famous novel The Kite Runner, a work of fiction that portrays the Afghan diaspora. This research study aims to explore the challenges, experiences, and identity crises of Afghans, as depicted in The Kite Runner, through a postcolonial lens. The study examines how war, displacement, class inequality, and cultural rupture affect individual and collective identity. Through multidimensional characters and intertwined narratives, Hosseini highlights the lingering effects of colonial legacies, the tension between self and other, and the “Third Space” of diaspora experience. Ultimately, the novel reflects resilience, nostalgia, and the quest for dignity in a fractured world.
