Khaled Hosseini's debut novel The Kite Runner takes the readers on a journey to explore the customs, culture, traditions, religion, ideology, and values of Afghan society. Hosseini has skillfully sketched the realities of Afghanistan illustrating two very different sides of Afghanistan: the first part of the novel where the country is a harmonious and peaceful homeland of the Afghans and the later part exposes the war-torn Afghanistan during and after Soviet-Afghan War and the Taliban control. Hosseini, being an Afghan-born American, through the life and events of his characters in the novel, gives an insight into his childhood world of Afghanistan - his motherland and the drastic changes that had occurred in his homeland after he left to settle in America. Each character in the novel represents the kind of individuals that coexists within the Afghan society, the morals and values they hold while dealing with situations, both good and bad. Amir's father is a man of culture, loves talking about politics, and has interesting views on religion. He has traveled to many places for his business, in short- an ideal successful man. But later in the story as Amir and his father migrates to America to flee the dangers of war in Afghanistan, Amir watches his father slowly and painfully crumbling. The novel can therefore be critically analyzed as American immigrant literature. While discussing the themes, humanistic, political, social, and moral aspects of Khaled's novel The Kite Runner, this research will attempt to cover the internal and existential struggles faced by the characters of the novel i.e., the struggles of an immigrant.
