Planet Earth has many secrets. Hidden within her skies, oceans and lands are different human species, some good and some evil.
One hundred and fifty thousand years ago human evolution took an interesting turn. Today, the Earth is dominated by Agrariens, unaware that other human species live in the shadows. But the time for hiding is at an end. The ghostly Aethiens want to rule the world and they have a plan. Only a hybrid boy named James Gaffey and a sky-dwelling girl named Aureole have the ability to save the planet, but first they must overcome their differences and work together. The whole planet is relying on them.
