This book was so good that when I got done reading it, I convinced my mom to read it, and now she convinced my mimi to read it.

very mysterious and suspenseful. has a lot of fighting, but it's very amazing you should read it. I'm reading the sequel it's so good so far. and, yee long story short, read it. plz :)

This book is so cool because charlie is a girl with an IQ of 220 who saves the world. What could be cooler?

The girl is a genius and a little thief. She is very smart and tries to save something called the Pandora's equation which was devised by Einstein. It showcases a character that is heavily anti immigrant and has a bit of violence to it though.

I loved this book so much because of the action, fun, and the one greatest genuis, charlie thorne. Pandora was an amazing thing that sopposeably Eintstein hid. I also read the second book and it was great too! Finding a lost city, the amazon, a temple made of gold and so many other cool things. I cannot wait to read the third and fourth books. I hope they will be great too. Stuart Gibbs knows how to write amazing books. Also, if you like this book read spy school series!!!!!!!!
