What happens when your entire life is ruled by a prophecy – your future foretold by people you’ve never met, who died long before you were born. Such is the story of two young sea creatures. One believed to be a guiding light for his people, a Beacon who will lead them to a bright, prosperous future. The other is a teenage prince for whose destiny is to KILL the Beacon so that HIS own people might thrive.
