Silence: Little Mermaid Retold

A little mermaid. A prince to save. Only silence can break the spell.
Once upon a time...
The mermaid Margareta saved Prince Erik from a shipwreck. Wanting to see the prince again, Margareta strikes a bargain with the Master of Beacon Isle. If she saves his sons from a terrible curse, he will reunite her with Prince Erik. All she has to do is stay silent until the curse is broken.
Silence is a virtue...until Prince Erik arrives early, searching for the mermaid who saved his life.
Can two hearts speak louder than words?
