Still REALLY enjoying this series. 
 The word that comes to mind when I think of it: fun. 
 I like the main character and the way Zoey responds to things. It feels real, like I'm listening to a close girlfriend recount all of her thoughts on something from the past. Furthermore, I like that she sounds very much like a teenager. It doesn't sound like an adult trying to be a teenager (like Stephenie Meyer, for instance), but contains slang and references very much in tune for someone that's sixteen years old. 
 Already excited for the next one!
