Aquamarine is your typical teenage girl, except for the fact that she's a mermaid...and one of the daughters of the ruler of the Ocean, King Neptune. Her father only has one rule to obide by, and that is that all mer people are forbidden to have any contact with the human world. What happens when one day Aquamarine witnesses a sinking ship belonging to none other than the infamous Captain Hook? Will she obide to her fathers wishes, or take a risk that changes her life forever?
