The paper examines how fantasy and faith contribute to the development of children's personalities through a textual analysis of three notable works of children’s literature: Skellig, Coraline, and The Devil’s Arithmetic. The study focuses on the fantasy elements of these stories, along with the underlying faith that sustains children's imaginative worlds, highlighting their importance in children's psychological and emotional growth. By exploring the characters, narrative structures, and thematic content of these novels, the research uncovers the mechanism through which faith in fantasy elements facilitates self-discovery and personal development of children. While doing so, the paper sheds light on the transformative power of fantasy in guiding children through their journey from childhood to adulthood. Additionally, the study discusses the enduring appeal and pedagogical potential of the fantasy genre.
