Under the Never Sky

I'm not really sure how I feel about this book. I liked Perry more than I did Aria. She was very annoying to me until the part where they reach Marron's. I was feeling like the book should have been more focused on Perry instead of Aria. The book was pretty average until about the last 80 pages. That's really when the book picked up for me and I ended up finishing it in like an hour. One thing I didn't like about this book was the lack of explanation for things I felt like where important. For example, The Aether and The Unity. I would really like to know exactly what the Aether is and where it comes from. I would also like to know what the Unity actually was. I am determined to read the second book in the series though because of the ending of this one.
