Y.H.T is an author-illustrator and the founder of Shine Works Books. Raised on a small island in Okinawa, she naturally developed a quiet habit of “consulting with herself” — a form of inner dialogue that helped her observe her thoughts and emotions from multiple angles. This lifelong way of relating to her inner world became the structural foundation of her debut picture book, The Opal-Colored Forest: The Magic of Metacognition. Her work blends art, psychology, and gentle philosophical themes. The book is designed with a layered framework that mirrors her inner-dialogue process: a surface storyline, symbolic motifs of light and the forest, and a deeper layer that invites readers to pause, reflect, and quietly meet themselves. As an illustrator, she uses AI strictly as a generative tool to visualize the images formed in her mind. Backgrounds and characters are generated separately under detailed direction, then manually refined—color, light, composition, and symbolic integration—until they align with her internal vision. All writing, pacing, and thematic shaping are created without AI. Her aim is to craft picture books that act as soft doorways: stories that end on the page but begin within the reader, guiding them toward their own inner forest.
