 2 words: Absolutely Amazing!!! Ally Carter has done it again, with this thrilling installment in the Gallagher Girl's series. I was anxiously awaiting this book, and trust me, it does not disappoint. After I was done with it, I wanted to reread it all over again. I laughed, I got teary eyed, and was blown away by the ending. I did know that something was up with Dr. Steve, but I was really surprised at Preston and his dad. This book was nonstop action, but I also liked that you saw a more vulnerable side to Cammie, instead of a tough-all-the-time spy. Ms. Carter did an excellent job with this book, and has made me love Zach all the more. I feel such a connection to Cammie because I have basically grown up with her. I first started reading these books when I was 14/15, and have loved the series since then. I am so anxious for the next, and final book. Hopefully someone will invent some sort of time machine so that I can get the book in advance haha. Even though I do not want this series to end, I look forward to the next book, and whatever books Ally Carter creates. I would highly recommend this book to any fan of the series, as it will surely have you wishing you were a spy.
