Polaris and the Goddess Glorian

"Polaris and the Goddess Glorian" by Charles B. Stilson is an early 20th-century tale about a young man named Polaris Janess, raised in Antarctica, who leaves the frozen wilderness after his father's death to connect with the outside world. Through dangerous events, Polaris meets Rose Emer, an heiress who is lost in the ice. They find their destinies tied to the ancient kingdom of Sardanes where the descendants of ancient Greeks dwell. Following clues left by his father, Polaris delivers scientific data, only to discover a man in shining armor at sea aboard the "Minnetonka", a signal of a much larger adventure that awaits them both in the underwater city of Maeronica, where they have to address political games, and powerful beings, on their journey toward bravery, fate, and knowing oneself.
