I suggest paying more attention to detail and perhaps adding some more description! Having more rounded out characters would help improv the story, too. I think your writing has great potential!
The plot is a good idea but the characters seem rather flat. There isn't a lot of development in the emotion of the story. It just seems like instead of developing the characters you force them to go through another traumatic experience. You also have the stereotypical supergirl as your main character which is also a flat character. Try going into further detail and have the things that your characters go through be little things that everyone can relate to instead of one big thing after another.
Don't really see a point inc ommenting on this since it's been a while I guess by the comments below. But I would suggest being a bit more detailed. I have a problem with that, too. But it's something I'm tring to work on. I'd like to get a picture of whats going on in the peoples lives. But other than that, it's good. But I hope you update soon or else my subscription would have been wasted.
