I really enjoyed this book. It's one of the most believable dystopias I've ever read. I had a feeling something like this really could happen in the future. I'm not sure if it's the premise or the writing, probably a combination of both. It also had the right amount of adventure and romance I love in young-adult fantasy/dystopia books. 
 The blurb, while accurate, is a bit too technical and confusing. If I hadn't seen great reviews for this book among my friends first, I may have passed the book up. 
 This book is set a few centuries in the future where the atmospehere is polluted with a dangerous substance called Aether. In this world there are two types of people - highly technologically advanced Dwellers who live in mostly underground pods. These people, who wear a device over their left eye, spend their lives in virtual realities called Realms. Their lives are touch-free, risk-free. The other group of people are Outsiders, who live in tribes and struggle to survive in the devasted world outside the pods where food and shelter is scarce. 
 In this world we meet our two heroes - Aria, a Dweller, who is thrown out of her home for a crime she did not commit and Perry, an Outsider whose brother is the Blood Lord of hos tribe and his nephew is fatally ill. 
 The worlds collide in the story when Perry and Aria, despite being disgusted by each other at first, form an alliance to help each other with their problems - finding Aria's mother and Perry's nephew. Of course, there's romance later on, but it's well-developed and does not overshadow the main story. 
 In the story two POVs keep swapping, Aria's and Perry's. It works here perfectly, not as a convient look into the head of both heroes. Their different world view comes out immediatelly and it's interesting to see the world from both POVs of a Dweller and an Outsider.
