No ordinary girl

A swim gone wrong causes my twin sister to begin to fear the water. She barely even touches it. I went missing when it happened, everyone thinks I drowned, and died. I did drown, or rather I started to, but then a bright light shown down on me during a full moon and turned me into a mermaid, one drop and 10 secs later a tail. I love it! I've always wanted to be a mermaid, our little sister was barely just born, I didn't know how to face my family, so I guess I just have lived in the ocean. I have all the girls powers, this was no accident, this is fate. This is amazing!
