I'm looking for an Avatar: The Last Airbender fanfic I read on Wattpad , but I can't remember the title or author.
          
          Details I remember:
          
          - The main character was an OC named Kya (I think), the older sister of Katara and maybe twins with Sokka.
          - She was a waterbender.
          - She could sing very good, she was praised in her village for her voice.
          - She had a scar from the Fire Nation raid that killed her mother.
          - The story started at the beginning of ATLA when Aang was found in the iceberg.
          - Zuko took/captured her early in the story, they traveled together though out the books and they eventually fell in love.
          - There was no love triangle; it was only Zuko/Kya.
          - In the Ba Sing Se arc, Zuko joined the Gaang instead of siding with Azula.
          - Kya was captured by the Fire Nation later, she bloodbendes ozai after he makes her sing and she  was rescued by Zuko.
          - Kya and Katara eventually learned to bloodbend without the full moon. Kya with ozai and Katara because she wanted to find her captured sister and rescue her from the Fire Nation.
          - The story was completed.
          - I remember the cover having fire and water intertwined, they made a heart i think.
          
          Does anyone recognize this fic or know the title/author? I'd really appreciate any help finding it!
