Kim Eun-hye is a Korean picture-book creator whose first written-and-illustrated book is My Dinosaur Age. The story draws directly on her own experience raising a child who became intensely absorbed in dinosaurs, transforming that family memory into a playful reversal in which the mother becomes the dinosaur. Kim is interested in the way parents and children learn to communicate by entering one another’s worlds rather than demanding immediate understanding. Her debut combines humor, empathy, and autobiographical observation, showing how shared play and time together can become a language of their own and how both parent and child grow through mutual attention.
