Under the Never Sky

Aria is a teenager who definitely has a big problem-she has been exiled from the alternate reality place that she calls home, through actions that in no way were her fault. Also-she can't get in contact with her mother who went to work on a top secret project. Knowing that she probably can't survive in the wastelands outside of her community, Aria panicks-until she meets Perry.
Perry is an outsider-not just in his small group of family and friends, but also in the literal sense. He and his family live in a tribe outside of the gated in complex of Reverie, a place home to people called "dwellers" who spend more then half of their time in a virtual reality. When his nephew is kidnapped by the Dwellers, Perry starts a journey to find him and do whatever it takes to do it.
Aria and Perry meet each other, and have to stop judging and stereotyping each other to start an alliance at first just for their own separate reasons that takes them through many adventures and eventually develops into a friendship and makes them see that there is value in both of their separate lives and bad things too.
This book was very good, actually. I didn't really like the characters, and the writing is only okay. But the storyline is so good that it kind of makes up for it. My favorite character is probably Perry or Brooke/Cinder (you'll have to read the book to find out who they are). I'd call this book adventure/sci-fi/teen-book style, and would recommend it to people in our class (there are not a lot of mature topics but some language).
