This is a world where earth and water have switched places, where humans live in the ocean trenches and mer-people live on the surface. We follow a small farm-boy, named Kaj Ragnarok, who lives in a small farming village, near the coast. He is friends with Aub Risan, the daughter of a wealthy trader, on the other side of the coast. The watery side. In this world, like any other, interracial relationships are frowned upon, so, what type of story will this be? Read and find out.
