The concept was interesting, but just about everything needed to be developed more. With the exception of Octavia (and she's not the main character), most of the characters were just thin caricatures of teen stereotypes. The characters were believable, but seemed to embody the more annoying of "typical teen traits". That said, it was an easy read, and it flowed well enough, and flowed into an ending that felt like it should have been around the midpoint of the book, not the end. More than a bit of a letdown in that sense. Just as I was really starting to get into it, it was over.
