Neurodiversity has gained increasing recognition in contemporary literature, particularly in young adult (YA) fiction, which serves as a crucial platform for shaping societal perceptions. This study explores the representation of Autism Spectrum Disorder (ASD) in YA literature, analyzing how autistic characters are portrayed in terms of authenticity, diversity, and alignment with real-world experiences. Through a comparative literary analysis, the study examines recurring themes, narrative structures, and the impact of these representations on readers' understanding of ASD. Additionally, it investigates the extent to which these portrayals challenge or reinforce stereotypes, considering the role of authors' perspectives, publishing trends, and audience reception. Findings highlight the progress made in fostering inclusive storytelling while underscoring areas where representation can be further improved. This research contributes to ongoing discussions about neurodiversity in literature and its broader implications for inclusivity and social awareness.
