What I like most about this book was the plot. It was dynamic! I really got into it. The build up of the plot, the secret code revealed was super cool. My only gripe was that you had to pay attention because the code was hard to grasp if you missed anything. A few times I had to re-read parts to understand what's was going on.Now the characters I also loved. The growth of the main character Gaia was good. I really like her snarky attitude and getting into her shoes. Through out the book you can really feel her coming into the part she plays. She's strong, courageous, and smart. I like that her beauty showed through who she was and jot what's she looked likes. Great book overall and great plot. I'm really interested in reading the next book!!
