Lily, a young mermaid, is forced to leave her loved ones and hide among the humans, escaping the war at home. She is forced to navigate high school and the extra complications of being a mermaid living on dry land. Lily ends up making unexpected (and handsome) allies and falls in love along the way. But the war isn't as far away as she thinks, enemies want the crown and will go to great lengths to take over. The only certainty is that both enemies and allies will fall...who will survive the war that crosses land and sea?
