Best PJ library book I've read yet! Full of adventure and suspense and interesting characters. I loved it!

In Charlie Thorne and the Last Equation, author Stuart Gibbs’ beautiful, lively writing will take you on a journey spanning the globe, from skiing off 50 ft drops in Colorado to zigzagging over rooftops in Jerusalem to stealing jets on the way to I-won’t-tell-you-cause-it’d-be-spoiling. This suspenseful mystery will have you literally holding your breath and rooting aloud for Charlie as she struggles to crack an immensely complex code in a world where nobody can be trusted. What Gibbs has written here is a witty adventure that will certainly be up to your expectations. Between the plotline and the writing, Charlie Thorne will have you up till 2am just to find out where Pandora is and have you so engaged in the story, you’ll soon be bouncing up and down without realizing it. If you like mystery, adventure, STEM, books about smart, brave, heroic girls saving the world, or just reading in general, then prepare yourself for Mr. Gibbs’ fantastic novel, Charlie Thorne and the Last Equation.

one of the best books everrrrrrrrrrrrrrrrrrrrrrrrrrrrr!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! not exaggerating! a few bad words though

I started reading this book as soon as I got it and had trouble putting it down. After I finished, I lent it to my best friend, and she loves it too! I have lent her some other ON Our Way books that had more Yiddish and Jewish topics that she didn't really get. This book has tons of meaning for Jews and non-Jews!!!

Very good book with a lot of history and action involved. Stuart Gibbs books are funny and loaded with action
