Deep beneath the surface of the water, a whole world goes hidden. The stories barely do it justice. They sing for you. They wait for you. They lure you. And then they drown you. When Delilah's voice lures over Evalune, she is surprised to find that the mortal girl is not enchanted enough to step into the water. Intrigued by one another, a friendship quickly forms and Evalune even helps Delilah by bringing people near the water. But Delilah is faced with a dilemma from the very moment she meets Evalune, and there is no escaping the rules of the underwater world.
