Lost Book - A Plea for Help

So it's been years since I've been on Wattpad and I decided to download it again to satisfy a certain nostalgia I carry for an old book that took a new twist on The Little Mermaid. But it's disappeared as far as I can tell. My heart is kaput. I'll describe it below, then in more detail in the chapter of this book.

If anyone could help me find it or even help me to simply recall the name of the book or of the author, I will be forever indebted to that person and will do my best to return the favor, as impossible as I believe that to ever be.

Okay, so the book was completed and was called something like "P______'s Prize." I think it was Parnamos's Prize or something like that, but it was definitely a magical type name. The story was about a woman who lived in a fantasy land where a certain numbers of years of charity work was required by the law and the world was divided into cultures by land, sea and air. If I remember correctly, a man from the air was brought up on her beach by a young mermaid and she had to care for him. The mermaid was madly in love with him, abandoning her family to be with him, but the man didn't have much care for her really. The woman was charged with the task of taking the mermaid home and reversing the curse that the sea witch had placed on her, despite the growing attraction between the woman and the man the woman loved. The woman displayed an unspeakable amount of selflessness as she sacrificed her feelings for the young mermaid and her older brother who was developing feelings for the woman (whom she eventually met when returning the princess before solving the curse).

(Will continue in the chapter since I'm out of space.)
