Interesting little read. Fun fluff. Not really scary scary, but enough to keep me interested. The adults are useless as are most of the teens. Many are just given names and are used as filler. Even Hannah's dad, who you might think would be an important character. If I saw my daughter changing the way Hannah was, I might need to have a few words with her.
I kept screaming at Hannah just like you do in the stupid horror movies. "Don't go in that room!" "Don't pick up the phone!" "Don't answer the door!" ... yet, of course, that's exactly what they do.
So for those of you that need a little light reading to zombify you, this one does very well.
