The story takes place on the oceanfront, in a tourist attraction called Ocean Wonders. Visitors pay to see wonders from the ocean including a possible glimpse of “Fish Girl”. Neptune, God of the seas, manages the boardwalk aquarium. Fish Girl does not know that Neptune is a businessman nor that Ocean Wonders is a business. To her, it is her home. Fish Girl starts to question many things about her existence, life in the aquarium, and Neptune’s rules. She wants to be free – free to come and go, free to experience life beyond the glass walls of the aquarium, and free to be seen. She learns the truth about the man who calls himself Neptune and how all of the sea creatures came to be in their glass prison. She wants something different for herself and her underwater family. To get what she wants, she must defy Neptune. In her journey, Fish Girl learns to question. Answers to her questions lead to change – she will no longer be a prisoner in Neptune’s glass kingdom and nor will her underwater friends and family.
