What if the Little Mermaid was born upside down?

Princess Ninon has spent her entire life as an outcast beneath the sea. Born with the head of a fish and the legs of a human, she is shunned by the very people she longs to belong to. While her fascination with the surface world grows stronger with each passing year, her mother's fear of humans keeps that dream forever out of reach.

Everything changes when Ninon rescues a drowning nobleman named Vivien Bellerose. Determined to see the world above the waves (and the man she cannot forget) she strikes a dangerous bargain with the sea witch Petraea. But as fantasy gives way to reality, Ninon discovers that finding a place where you truly belong may require more than changing who you appear to be.

A curious bookworm with an endless fascination for the human world, Princess Ninon has always dreamed of seeing the surface with her own eyes. Gentle, polite, and compassionate, she never lets years of rejection extinguish her sense of wonder.

Shunned by her fellow merfolk for being born "upside down" Ninon struggles with deep-seated insecurities about who she is. Yet beneath her timid exterior lies the courage to pursue her dreams even if it means venturing into an unfamiliar world.

The eldest son of the House of Bellerose, an altruistic nobleman who possesses deep faith in the Lord and a talent for composing music.

He became indebted to Ninon after she rescued him from drowning one fateful night...
