I have to say I am not a huge audible fan, but if all audios were as fantastic as this one, I would listen to them a whole lot more.
I really loved Ezra, and Kady so freaking much, and how cute were they, when they communicated with one another. I really thought the story and some characters were really pretty awesome. I got chills going up my arms whenever the voice of Aiden came into play. I still can't decide if I liked Aiden or not. I could understand its logic but not how it went about it. I don't want to say to much about the story, because I am afraid I would give a lot of spoilers out. The ending was just super WoW, I would actually say the whole second half was just freaking creepy and Nuts. And it took you on a Freaking Awesome, fantastic, and one hell of a ride. I would definitely recommend this book, especially as an audible book if you could afford it. Also if you have the book, get the audible and following along with the audible with the book. Because the book in regards to how it's set-up is not to be missed. I only have the e-book for this one, but for book two, I have the e-book, audible book, and hardback, as well.
I can't wait until I have time for the second book, and for the last one in the series to come out.
