Charlie Thorne and the Last Equation is an AMAZING book! I got absolutely lost in the book and read it really quickly. There were a lot of twists and turns, plus the fact that is a genius. The author, Stuart Gibbs, is a genius. When i found out there were more books in the series I absolutely FREAKED!!!!! I hope everyone who reads this enjoys it as much as I know I did. ( For adults to know, my mom read the book and LOVED it too. )

Oh, and this was the best book I've ever read from the PJ Library selection. Really happy I chose it!

I loved this book so much, it was so much fun to read. I quite literally couldn't put it down. It was especially fun to read in the evening for some reason, but that could just be me. It makes you want to know more every time you put it down, and I haven't found a mystery book in a while that made me keep going. Especially since mysteries aren't exactly my favourite book genre. And this book was great--no, amazing!!! So who knows? Maybe I'll start liking thrillers and mysteries more. And apparently, this book is a part of a SERIES. I'm definitely going to read the next one. Hope you like it as much as I did!

I won't give anything away, but this book has an amazing plot filled with twists and turns. The author is really talented and wrote one of my favorite series, Spy School.

Really good book, it keeps you interested in it. READ THE SECOND BOOK ALSO! (if you like it) I recommend for ages 9+ .
