Great work
I actually really liked the plot. The ending was sad, but at the same time fit perfectly. That Bly family... Wow. Part of me wants to see a sequel dealing with the new president and how that all goes, but I don't think that would fit in with the original premise of this book at all.
I got side tracked. Overall I think the writing style is good, however sometimes I found myself forgetting how young the central characters are, which then got frustrating at how trusting Emmary was for the majority of the book. But that might just be me. Also I'm still trying to decide how involved Hal was and how much was an act.
Also I think you could benefit from a beta reader, as there are a few typos in many chapters that your spell checker wouldn't pick up (eg quite instead of quiet, you/you're etc) and can be hard to spot in your own work.
Overall, however, I think it was a great story. :)
