When the four choices for this month came up, I didn't really want to do this book, I thought it would be boring. You know a genius finding an equation? Meh. But my mother told me to get it. She told me she thought I would really like the book. I got the book. And when it arrived, it just happened I was starting a book report at school that week. I didn't really have a book, so I just took out this book from on the shelf and said Fine. If this book is a bummer, I will just ditch it and get another. But once I started it, I could not stop reading. If you know me, you know that once I get into a book, there is no stopping. I am immediately separated from the real world, transferred into the book. I don't hear what is going on around me, even if there is music blasting! Overall, what I am saying that this book is just AMAZING and I hope you will all like this book as much as I did.

this book is off the charts. if you dont read it, it means you dont like good books DUDE

This book taught me more about Israel-I never knew about the Mossad. This is a good book for people who like learning things. The only thing about Albert Einstein that I believe is fiction is Pandora's Box. And by the way, now I have a periodic table(when I looked in my dictionary there wasn't one)! To know what I mean by all this read the(very good in my opinion)book.

The best book. Didn't even have to read the cover to tell it was Stuart Gibbs. Great plot. Adventurous and suspenseful.

Great fast paced spy novel. With a female protagonist. A fun, interesting book full of plot twists and surprising mysteries and codes.
