Since the beginning of Mu there has been a prophecy. Twins born of fire and water will lay waste to the island. For the sake of Mu’s inhabitants, no twins can survive. Or else a catastrophe of volcano and tsunami will annihilate them all. Kaori and Kairi are forbidden twins, two halves of a whole, the first to survive on the ancient island of Mu. One was born of fire, the other of water. As the twins are pulled in opposing directions, and hatred reaches a boiling point between the two, many will die in the crossfire. Will Kaori and Kairi unwittingly enact the prophecy and destroy the island of Mu or can one twin stop the other from bringing about destruction. . . ?
