This novel depicts the problems involving alienation, isolation, and self-identity crisis that the immigrants face as the minority and outsiders in the American society. This novel takes the structure of detective fiction, developing a story of a spy who investigates an ambitious politician. Its main action concerns an amazingly charismatic New York City councilman, John Kwang, the idol of thousands of immigrant voters in his home district of Queens. Someone wants to see him go down, and it is Henry's job to provide the dirty laundry. Also this story of trust and betrayal is connected together with other, more delicate threads: his troubled relationship with his traditional Korean father, his troubled marriage to his American wife? His Confucian inability to express live to either of them except through silence. Beautifully written and intriguingly plotted, the novel interweaves politics, love, family, and loss as Park starts to make sense of the rhythm of his life. As he does, his experiences illuminate the many-layered immigrant experience in general, and the Asian immigrant experience in particular, in a way that many readers will understand and appreciate. Through the life of Henry Park, the author exposes the alienation and isolation that many immigrants and their children faces from the American society. Also he depicts the conflicts between 1st generation immigrants and 2nd generation America-born children caused from the cultural differences and the incompatible perspectives toward their lives. Through the motif of a spy, the author successfully creates feeling of uncertainty of identity and place from a point view of a perpetual outcast looking at American culture from a distance. Beginning to fear That he has betrayed both Korean and American worlds and belong to neither, the only thing that Henry Park acquired from his life as a spy and an outsider is the confirmation of his true identity filled with pain and sorrow. There are many qualities of this novel that resembles the qualities of Romanticism of Great Gatzby as Henry Park, the hero of the novel, quests for truth of his identity and displays a strong disbelief toward civilization and love toward the nature. Also Henry Park has some characteristics of the hero of Hemingway such as NADA, inability to sleep during night, and the belief of grace under pressure. Who am I? This question is thrown to the author, Chang-rae Lee himself as well as to Henry Park. Even though he immigrated to United States when he was only three, graduated from the Yale University, and established himself as Native Speaker who uses the English as his native language, he still feels that he is an outsider who can not assimilate into American society. For this sense, we could view this novel as author's honest experience of his life. The novel Native Speaker approaches the readers as an important meaning for it deals with racial problem, a peculiar aspect of American society, and boldly exposes the alienation of modern people.
