Okay so I really, really liked this. You did a good job in the summary with telling the reader what they need to know without giving the entire plot away and without making it boring to read.
In the First Chapter
"...pushing him away into the racks we had been just a few minutes ago." ^ I think you should add "where" before "we"
"...the window, willing Em to be following me, and I heard..." I think you should change "willing Em to be" to "hoping that Em was following me"
Those are the only two things that I can pick on. You did a really great job with this, and I'm going to subscribe.
