A fifteen-year-old Jane Buxtom decides to set out to find her missing older brother. Chasing after a mysterious hint of her brother having found the secret of ‘Cerulean Sand’ at the time of his disappearance, Jane begins an adventure that will lead her from the safety of her English manor house to the vast foreboding deserts of the Middle East and then to isolated mountain trails somewhere in the Caucasus. Chasing after various clues appearing only as hushed rumors and forgotten legends, Jane and her (protective) fellow travelers find themselves having to fight off a band of soldiers equipped with strange airships, who are seemly intent on keeping the ‘Cerulean Sand’ a secret to all outsiders.
