This needs a lot of work--I'm going to be honest here. You need to clean up your grammar--bad grammar can be distracting, though I notice they're people who don't seem to care. Another technical problem I have with this this is your "POV" change method. You don't head a POV change like a chapter, you write it in a manner that makes it obvious that another person is speaking. There are some great writing books out there, some of whom focus strictly on POV--you should check one out.

For me, personally, You made the initial story about Emma too long in the story's beginning.. Try and find a way to shorten it and then get back to it. It made it rather confusing--is this Emma's story or Scarlett's story? I think the story belongs to Scarlett, so get her in there earlier.
There is so much going on here that it gets a little confusing at times. Like I said, I think you need a re-write, and from my personal point of view, I don't understand why you chose the ending that you did. To me, anyway, it didn't seem to make sense.
As I said a couple of times, this really needs a re-write. If it sounds harsh, just remember that I'm probably a lot more experienced than you, and that other people have been harsh and honest with me. It's the critics that make us a good writer because they challenge us to do better. My "Ghost Girls Chronicles" received a lot of criticism as well as praise when I first posted it on URBIS (which is defunct now) and I can honestly say they helped make me a better writer
