Writers and scholars have used a variety of approaches to understand novels written in English about Afghanistan. One approach that most of the writers have used is the sociocultural approach. My approach is quite similar to other researchers but my framework is different. My work focuses on an unwritten code of life, Pashtunwali, which the Pashtuns of Afghanistan have been practicing for centuries. This code strictly guides the lives of Pashtun people living in Afghanistan and North-West Pakistan. By using the framework of Pashtunwali, this thesis provides a new perspective and understanding of Hosseini, Hashimi, and Ackerman’s novels. It not only provides a different perspective, but also helps readers to understand these texts in the Afghani cultural context. Some of the key topics that this thesis discusses using the framework of Pashtunwali are honor, revenge, blood feuds, hospitality, role of religion and culture, marginalization of Afghan women, and the system of justice. Thus, the goal of this thesis is to provide a new dimension for readers who are unaware of the cultural codes that people practice in Afghanistan and to highlight the social issues and problems that Afghan people face. Not only does it highlight those social concerns, but it also traces their root causes.
