- Best book in the series by far!!
- This book was more intense and mysterious. It was more of what I expect out of the spy book. I couldn't stop reading.
- The story reminded me of the Bourne Identity movie.
- Cammie is definitely not the the same girl she was at the start of this series. She has experienced a lot, and it has changed her.
- I LOVE LOVE LOVE that this book ties into the previous books. I want feel like I missed so many clues that became important. I want to re-read the series to catch everything. Very clever Ally Carter!
- I'm glad I stuck with the series. It wasn't really going places, but things have changed! I wish it had gotten this good earlier, but I understand the build up now.
