this is a good first chapter, in some ways its like other dystopian stories, with a sci-fi like twist. Everything moves at a good pace, and I'm looking forward to reading more.
You have a natural talent for story telling. Most sci-fi stuff I've skimmed hardly contain my interest but your pacing is really good. The introductions of characters were smooth. Although it does seem to follow the teen dystopian stories out there, I'll have to see what this one develops into.
The story was decent but it seemed too much like a cliche dystopian story like the hunger games of divergent (examples are the usage of capitalized words like the Occupational selection and the "Nightstalkers" the use of a female protagonist and the strange clan/conformity-system society)
I had to start somewhere, and if you've read further you'll see that I've moved in a better direction... It's definitely a work in progress, I hope you keep reading.
