There is so much about this novel that I really loved. First off, yes, this is essentially a zombie story; however, just like the original Night of the Living Dead, the "z word" is never uttered. Instead we are given a somewhat clinical explanation as to what is infecting people. I like that, I felt like it stayed true to the history of the zombie genre. The book struck me as The Walking Dead for the high school set; again, I think this is a good thing.
I really liked the characters of Kennedy and Harrison. I thought they were well developed and had a rich, dimensional role in the story. I liked that Kennedy was a strong female character, in many ways equal, if not superior to, Harrison. I also liked the romantic storyline between the two characters. Even in a world full of chaos, love can bloom.
The story seems to be marketed to young adults; however, there is enough of a storyline to also engage adult readers. The book ends a little abruptly, mostly to hook the reader for the next installment of the series. All in all, I thought this was a good book, proving that there is still life (reanimated life at least) in the zombie genre.
