Between the Sea and the Sky: The World as Seen by a Young Girl Named Nadia—A World Evoking the Late 19th and Early 20th Centuries

Nadia: The Secret of Blue Water Set in a world reminiscent of the 19th century, this work depicts the adventures of a boy named Jean and a girl named Nadia. The story unfolds by intertwining machines that symbolize modern science—such as airplanes and submarines—with the mysteries of a lost ancient civilization. Jean is a boy with a keen interest in science and invention, while Nadia harbors secrets about her birth and past. During their journey, the two encounter many allies and enemies and become embroiled in a massive conflict that threatens to shake the world. The appeal of this work lies not only in the excitement of an adventure story. It repeatedly explores the issue that while science and technology enrich human life, they can also lead to destruction if misused. Furthermore, themes such as the development of civilization and nature, human desires and responsibility, and the value of life are woven into the fabric of the story. It is an epic adventure tale that depicts the growth of young boys and girls while posing the question of how science and humanity should coexist.
