This book is AWESOME!!!!!!! It’s about a really smart girl who has to find Albert Einstein’s mysterious Pandora equation. (I love math so this book is really cool to me!)

I think this book is kid-friendly but there are some “adult-ish” almost jokes in the book. The girl says at one point that the 2 unmarried agents should take the bed… She also says that the agents wouldn’t mind a little kissing before bed… “Bleh!” I wasn’t sure why that was in the book, but it is. I still think it’s kid-friendly, but maybe ask your parents first.

There is also some violence in the book. I think there were German terrorists who really wanted the equation and would “ahem” kill for it… (And surprisingly, I still think it’s kid-friendly) There was also a lot of guns, bullets, dead people, fires, people “in” fires, and over all violence… But the book was very clean and didn’t describe that much, so I’m still going with Kid-friendly. (But maybe 8 and up kids)

Over all, I totally suggest this book. Stuart Gibbs has written another book that I just LOVE! I hope you all love this book as much as I did. -The Young Llama Reader.

Charlie Thorne is a genius.
Charlie Thorne is a thief.
Charlie Thorne isn’t old enough to drive.

And now it’s up to her to save the world…

Decades ago, Albert Einstein devised an equation that could benefit all life on earth—or destroy it. Fearing what would happen if the equation fell into the wrong hands, he hid it.

But now, a diabolical group known as the Furies are closing in on its location. In desperation, a team of CIA agents drags Charlie into the hunt, needing her brilliance to find it first—even though this means placing her life in grave danger.

In a breakneck adventure that spans the globe, Charlie must crack a complex code created by Einstein himself, struggle to survive in a world where no one can be trusted, and fight to keep the last equation safe once and for all.
