The Siren's Mortal Queen

Illegitimate daughter Leora is cast into the sea by her cruel family as a political pawn. She is saved by Adrian, the mighty siren king, and becomes his queen. After bearing a son with a fish tail, she flees in terror, only to later uncover the king’s secret identity.

She braves deadly danger to obtain the antidote for the gravely injured Adrian. The king reveals his true siren form to crush a palace rebellion, and they wed in a sacred deep-sea ceremony. Leora finally settles scores with her abusive birth family and finds lifelong love and peace.
