I don’t understand how she’s 12 and in college

This was amazing! It's great to finally have a Stuart Gibbs book with a female main character!

Charlie Thorne is such a great book series. LOVE IT. 5/5

Like the title, this book is probably the best book I’ve ever read! It has adventure, exciting twists and turns, geography/history, and much more! There are two other books in the series after this that I highly recommend! The second book is called: Charlie Thorn and the Lost City. The third book is called: Charlie Thorn and the Curse of Cleopatra. I showed this book to my mom, and a bunch of my friends and it is good for almost all ages. (Including adults who are looking for their next awesome read!) (Or kids who have been told to read by their parents but have no good options. I’ve been there.) I’ve probably read these books about five times over this past year! There are SO MANY more things I would say about this awesome book but then you would probably be reading this review for hours!!!! I give this book INFINITY OUT OF FIVE!!!!!!!!!!!! I highly recommend and if you did/do choose this book, I hope you enjoy it as much as I did!

Charlie Thorne and the Last Equation is by far one of the best books I've ever read. I reread it maybe three times before I was told by my school librarian that there were two more books in the series. It made me feel elated, and scared me at some parts. It's full of adventure, with lots of twists and turns.
