In this thesis, three novels of contemporary Croatian children's and young adults literature are analyzed: Zagrebačka priča by Blanka Dovjak-Matković, Smogovci by Hrvoje Hitrec, and Mrvice iz dnevnog boravka by Sanja Pilić. The theoretical part of the work provides a detailed explanation of the narrator, their role, and significance in the narrative structure. The first part of the thesis is based on a theoretical framework that includes analyses of narrators and narrative techniques, with a particular focus on different types of monologues and dialogues. The analysis examines how the narrative voice and style are used to shape the story and characterize the characters, as well as exploring specific narrative techniques employed by the authors to create complex and dynamic narratives. Infantile narrators often deviate from grammatical norms, use colloquial expressions, and rely on fantastical elements and imagination, which further highlight the child’s perception of reality. These novels, through their narrative structure and style, reflect the social, cultural, and psychological aspects of life in 20th-century Croatia, while simultaneously addressing universal themes of growing up, family relationships, and societal challenges. Through the analysis of these novels, the aim is to depict how various narrative strategies influence the portrayal of themes, characters, and relationships in children's and young adults literature.
