Your plot idea is good, and you've clearly planned out the charcter of Sammy very well - but perhaps you could tell us about her and her background more gradually, so we can get to know her too instead of simply being told everything.

The grammar and spelling is a bit clumsy and makes the piece hard to read - I think a lot of people will be very put off by this. Perhaps you could spend some extra time after you finish writing a chapter going over it and correcting errors? Or you could get a Beta reader to do this for you - I'm not actually one, but if you want me to lend a hand, I'm happy to :)

The pace is a little fast too. If you could slow it down, taking more time to focus on descriptions, people, moments, it might improve it a fair bit.

I'm interested to see how this is going to progress :)
