I read this book, and then my brother read it because he saw me reading it. really suspenseful! my brother is @marblemaster

Really good book. Very suspensful and kept my attention all the way to the end. Parts were hillarious. I definitely recommend this book.

I agree with VBookworm, Stuart Gibbs should get an award! (He might already have) Charlie Thorne and the Last equation is and thrilling, suspenseful, adventure, in which a 12-year-old genius alongside the CIA chases after clues, thought up by by Albert Einstein himself, racing to beat the bad guys to something that could save or destroy the world. each chapter (more or less) ends on a cliffhanger--even the last one. Read this book, or else!!!
