If you have ever read any book that Stuart Gibbs made you will know that she is an amazing and fantastic author making this book no exception. Charlie Thorn and the last equation is a book filled with secrets, adventures, action and a bit of romance. I would recommend this book to everyone who is reading this. If you do read the book you should also read the others in the series.

I absolutely LOVED Charlie Thorne and the Last Equation. It was an awesome book and so were it's sequels, Charlie Thorne and the Lost City and Charlie Thorne and the Curse of Cleopatra. I would recommend the Charlie thorne books to kids 8 - 13. I really hope Stuart Gibbs makes a 4th book in the Charlie Thorne series. I definitely recommend Charlie Thorne and the Last Equation. The Charlie Thorne series also teaches you a lot of history and geography stuff.

It has mild violence but is in general an A+++++ book! Make sure to read the whole seriese.

This is my new favorite book. You have to read the book series
