It is the first novel of Hosseini which had been one of the bestselling in New York Times ranking list. It studies Hassan's tragedy from three aspects, including the social environment in Afghanistan, the loyalty of Hassan, and the selfishness of Amir. Besides, it also discusses the friendship and betrayal between two boys-Hassan and Amir. Finally, the terrible life of Hassan in Afghanistan is under investigated.展开更多
