Oh I honestly couldn't tell you my favorite part, it's all really great. I just love how detailed you are, and the pace. The pace is absolutely perfect; not too slow, not too fast. You don't rush it like most people and that makes it a great read
If I had to pick, my fave part(s) is/are probably anything to do which Jackie's relationship with Sam. I'm interested to see if you have him to continue to distance himself or becomes friends with her. If you don't write again soon I'll probably have withdrawal hahaha. But good job so far!
