Seshi belongs to the ocean, not to the human world. But that doesn't stop her from leaving behind everything she knows.

Shocking her restrictive and dangerous family, she removes the necklace that allows her to change into a mermaid – the magical emblem of who and what she is.

After several years, Seshi decides to return to the family who assumes she is weak and foolish.

But Seshi is far from powerless. She has a secret only she knows. And when she returns, it will be for revenge.
