Secret of Cerulean Sand - S01

Jane's mother dies giving birth to her, and her father, a wealthy English aristocrat, soon remarries a woman who already has a son, William, who despises his new father and brother. George and Jane grow up dreaming of building a flying machine. George believes the distant Asian sands hold a secret: a mysterious cerulean sand that can make machines fly. He sets out on an expedition to find it, and is soon reported executed for treason. William disappears as well. After she receives an unsigned letter holding a handful of pale-blue sand that floats in the air, Jane is certain her brother is alive and sets off for the East to find him and prove his innocence. Many mysteries await Jane and her new friends on her journey. But perhaps some mysteries should remain mysteries forever...
