This study is based on 72 children's and young adult books that met the criteria of being about Muslims and published and circulated here in the U.S. They can be divided into the varied genres as 49 contemporary realistic fiction, 6 historical fiction, and 17 autobiographies, biographies, and memoirs. In-depth reading and coding were used to identify patterns based on a theoretical frame of postcolonial theory and the lens of cultural authenticity.The exploration of ideas focus on the following research questions related to children's and adolescent literature published and distributed in the US that depict Muslim cultures: What are the overall characteristics of the books? What are the background experiences of the authors, illustrators, and translators who write and distribute literature within the U.S. that reflect Muslim Cultures? How do the genres of contemporary realistic fiction, historical fiction, and biographies published for adolescents and children within the U.S. represent and frame the varied Muslim cultures? What are the relationships between the background experiences of the authors and the representations of Muslim cultures in their books?This work is grounded in the assumption that Muslims are presented in a certain manner in popular culture and literature in the U.S., and thus, postcolonial theory is relevant in unpacking issues within the literature about these people. This theory draws on these suppositions to unveil how knowledge is constructed and circulated in dealing with global power relations. It also sheds light on how the identities of natives become hybrids as the process of colonization in certain cases impacts the psyche of inhabitants of these regions.This study is a `critical content analysis' in comprehending how texts are based in the social, cultural, and political contexts in which they are created and read. Content analyses examine what texts are about, considering the content from a particular perspective. This method scaffolds and explained my research to support my analysis of the texts through postcolonial perspectives to observe how Muslims are portrayed within adolescent and children's literature in the U.S.
