PlanetC Stories is a creative publishing and art brand founded around the books and artwork of Cathrine L. Wilhelmsen. It offers illustrated stories that bring imagination and emotion together, helping children and adults explore feelings, relationships, and how to understand one another.

Written for children of all ages, with words adults can borrow, the books address themes including inclusion, courage, belonging, loneliness, being seen, and family change. Featured titles include Tusen ønsker, Julia og nordlyset, Perlehviskeren, and Gunnars gresskars verden. Books and e-books are available in Norwegian and English, alongside art prints offered with or without frames.

The stories are designed for shared reading and conversation at home, in nurseries, and during quiet moments together. PlanetC Stories presents its work as warm, thoughtful, and imaginative, with an emphasis on beautifully illustrated storytelling and emotional insight. Its online store also shares book recommendations, a guide to choosing a suitable title, blog content, customer reviews, and information for following orders
