Synopsis by Sandra Brennan
In this Japanese sci-fi adventure, Japan and the rest of the planet is being destroyed by a deadly series of earthquakes. Explorers soon discover why: beneath the sea is an enormous city, Mu, and to keep it going, they have been stealing energy from the Earth's core. They refuse to stop and so the Japanese government pleads with the commander of the air, land, and sea supership, the Atragon, to help them destroy Mu. Unfortunately, the skipper cares nothing for saving the world. But when the Mu-folk steal his own daughter, the commander changes his mind.
