The Aether storms, the senses, the pods, the realms, it was a lot of science fiction. I'm not big on science fiction but I do get into it occasionally and this book worked for me. The concept of the realms is kind of cool, but scary at the same time. You're "living" your life without physically doing anything. Creepy. 
 I loved both Aria and Perry. I enjoyed Aria's self discovery of her real self, though there was one really weird moment that had me laughing and cringing at the same time. It was awkward. The things that Perry went through were just awful. I can't imagine making some of the choices he had to make. 
 I loved the ending. It reminded me of Hunger Games or the Harry Potter books where the story in the book had an end. It wasn't a happily ever after end (it's a trilogy so lets not get carried away) but it has an end, and then a little extra to give you a taste of what's coming. 
 My one complaint about the book is the lack of information. You're thrown into the story (which is ok) but as the book progresses there were a lot things that were never explained, or only given a partial explanation. The "reason" why everything happened was one of those partial explanations. 
 Overall I really enjoyed the book and I'm looking forward to the next book in the trilogy.
