Among the spared, magic chooses a rare few, connecting them to the moon or sea. These are the One-Hundreds, mermaids and humans with the power to save the world-or corrupt it. When Cressa-la breaks the first rule of her tribe and touches the water surrounding her island, everything she knows turns on its head. Talking, sinister dolphins, mind control, and a whole world just under the waves await her on her eigteenth birthday... but she never asked for any of this. All she wanted was to become a Tribe Leader and take care of her village. It's amazing how one screw-up can change everything.

Unless Cressa-la can bring the darkness to his knees and fight the war raging inside, the world is doomed. • • • Content warning: This story contains themes of depression and violence.
