It was kind of exciting but I didn't feel to interested in it.

In the book, Charlie Thorne had to find an equation for the CIA (and her half brother) before a terrorist cell did. It included a lot of adventure and action. Definitely read it!

I really loved this book. It's just awesome, and you HAVE to read it.

A great book with a greater plot and even greater characters! Super cool female protagonist and some awesome Einstein facts. Also some pretty rad action scenes! All around amazing.

I started to read it and couldn't put it down.
