I really really loved this book and would have gladly given it 5 stars - if it weren't for two things: 
 1. Kell and Lila didn't (view spoiler)[ meet again until 426 pages into the book. FREAKING FOUR HUNDRED AND TWENTY SIX PAGES! Considering that the whole book only has 508 pages and they've both known they were in the same city since about page 250 that was unbelievable frustrating and honestly felt a little forced at some point. (hide spoiler)] 
 2. Sometimes Lila was a little too much for me. It's one thing being strong and fighting for what you want. Lila tended to take that one step too far though, so she went well past being a strong woman and into selfish bully territory where she just took what she wanted, other people and consequences be damned. The sheer arrogance of her nearly drove me crazy once or twice during this book. 
 Thankfully there are two sides to her tough and I absolutely loved that other side. And over the last 100 pages of this book I kind of forgot about everything I might have not liked in the beginning. AGOS turned out to be a fun, intense and surprisingly emotional journey. I fell in love with Kell all over again (whom I wanted to wrap up in a blanket and hug most of the time) and I learned to really appreciate Rhy in this book. There's also one particular new character who will hopefully play and even bigger role in the third book, he is just that awesome. 
 All in all a strong sequel that dragged a little in the beginning when very little happened but thankfully ended up being brilliant. :)
