Miranda fights the pull of the glittering, beautiful undersea kingdom, her blossoming feelings for the smoldering king and the deep friendship with Robbie. But danger lurks under the glittering water. Miranda quickly discovers that even underwater, people have secrets….dangerous secrets which could cost her all she holds dear.
