My mom and I adore this series. I am obsessed with the CIA and spy stuff (so you'll know I must like it). This book is about a 12 year old girl who somehow gets into a lot of trouble for her age. She is a fugitive. This feisty young lady has stolen a lot of money which she calls her own and goes on a mission to find Pandora's Box. I don't think her brother likes that very much. ..you'll find out later on that one! I highly recommend this book if you like action and suspense. One of the best ever!

Super good book!!!!!!! Get if you have the chance!!!!!!!!

I liked the book. There were a lot of action-packed moments!

I loved Charlotte Thorne and the last equation!!!!!!!!!!!!!!!!!!!!!!!! There was so much suspense . I liked Dante Alejandro Garcia (DAGger)'s torrid romance with Milana Moon I rate this book a 10/10

This tells the story of a twelve year old girl who goes on an adventure that leads her to find the most important equation ever created in mankind. Sound exciting? Well, it totally is.
