Mermaid’s Broken Vow

Fifteen years ago, mermaid princess Miranda gave up her tail and came to the human world for Arthur, believing his vow to love her forever. Ten years later, Arthur betrayed her for a wealthy heiress, even tearing out her royal scale and causing her to lose their child. Heartbroken, Miranda returned to the deep sea, where Caspian helped her rebuild her life and destroy Arthur’s company.
