This book is so good I can not explain it in words. Seriously...read it it is so worth it!

This book was so interesting, so intense, and just so awesome! There are a few violent parts, but overall it's one of the best books I've read! I highly recommend this book! I also am not so into action and all that, but this book was the best!

I Love this book! Anything by Stuart Gibbs is great and totally recommended. I am so glad that he involved Israel in this book so I could get it. I can't wait for book #2!!!!!! And the Spy School movie.

This book is soooo great! I could read it over and over. An absolute must read!

this book is so good and i read it so so so many times, and that's saying a lot because usually i don't read books more then a few times for a while. the only REALLY disappointing part was the ending. it was a good ending (meaning, it ended out happy), but it never really, like, explained the final equation (you'll know what I'm talking about wen you read the book). but, its still an awesome book and i love it.
