Throughout the book there is action, mystery, crazy equations, super awesome Einstien facts, surprises, smarts, and silly jokes!!! Half of the the time you are on your toes to see what Charlie does next then You are completely surprised about all of the characters choices! These characters are also completely believable and make bad choices.... which is a perfect thing for a novel like this to have! This is a great book - and also quite unique - and I wholeheartedly recommend!

This was awesome i can not put it down super good plot one of the best books i ever read lots of twists and turns i have read soooooooooo many books this one caught my attention and i could not put it down till the end. PJ library is setting the bar for them selfs this book is hard to beat.

This book was great. I loved all of the fighting and action in this book.

I have read many books, and this one is among the best. There is a fair amount of violence, but the story is great and fast-paced. If you like mystery, or action, or just a book that is SUPER GOOD, I would recommend Charlie Thorne and the last equation.

This book was great! The best plot along with a right amount of laughter. I read it in like 5 days WOW
