    This book is awesome and I am so jealous of Cruz right now, If you are interested in codes and puzzle solving there might not be a better book than this the best part is that it has pictures in it which made it so easy to visualize what was happening and over all i love this book.

              This book is full of adventure and I LOVE adventure! I liked all of the characters but especially Emmett with his cool changing glasses. I also loved the descriptions of all the delicious food Cruz gets to eat at the Academy. It made my mouth water every time. I highly recommend this book.

                This book is great! There was a picture of this chart that had symbols that means the alphabet.There were lots of codes in the book. It was fun to break the code and see the message. I can't wait to read the second book in the series, The Falcon's Feather!
