Cross My Heart and Hope to Spy  - Ally Carter This review was first posted on Music, Books and TeaI thoroughly enjoyed the first book in the Gallagher Girls series, and knew that I had to continue on with the series as soon as I possibly could. Cross My Heart and Hope to Spy was a great continuation of the series, and has just made me more eager to continue reading this series!Cammie has really grown as a character, and tries desperately to work out the balance between being a spy and being a normal girl. At the beginning of the book she decides she’s going to stay on the straight and narrow, but we all know that it would never work! She really cannot ignore her spy instincts, which is both good and bad, and I’m pleased she accepted that at the end of the book! Her antics in this book really made me chuckle, she really is a girl when it comes to dealing with the opposite sex! I did feel really bad for her however when she tried finding out the story behind her dad’s last mission. And I got really cross when she was told she needed clearance to hear the story of how her parents met. I get that spies aren’t allowed to divulge top secret information, but that really did feel like a poor excuse from her mother. We’re introduced to Zach, a male spy from the male version of the Gallagher Academy. I’m not entirely sure where I stand with Zach. At times I really loved his character, and other times he was a total idiot who played way too many games with Cammie. It took until the end of the book for me to warm to him, and I think that was partly due to the fact that we don’t get to know Zach like we got to know Josh in the previous book, but that just highlights the difference between the two. And I can’t deny the chemistry between Cammie and Zach, so I hope we get to see more of him in future books.The final mission at the end of the book was fantastic! It was full of action, which I loved, and it was great to see Cammie take charge and give out orders to people. There was also a lot of humour in those final scenes, just like there had been throughout the entire book, which I enjoy. Ally Carter has a way of writing funny scenes and dialogues that never feel forced or stick out on the page like a sore thumb. Everything flows and reads fantastically, which I love.I can’t wait to see what happens to Cammie and her friends next. I just know that if the third book in this series is anything like the first two, I am really in for a treat!
