Gaia's Prophecy: The Fabulous Adventures of Kiso Maravillas, Book I

On a planet much like Earth, Gaia has unleashed water to cleanse the world of the people who misuse her. All of the land is flooded, and its inhabitants must adapt or perish. The animals seek refuge in the depths of the ocean. Humanity is forced to live on overcrowded floating platforms with limited resources, governed by tyranny and cruelty. But not all the platform dwellers are the same, and some leave the platforms for the seas to make a new life, wishing to live in harmony once again with the planet.
