Exciting book!

I loved reading this book, the suspense was great up until the very end. My nose was in it until I finished reading the entire book.

This is a great book and it kept me in suspense.

this book is awesome it had a great storyline. I loved learning about Albert Einstein!

I loved reading this book so much that I read it in 3 days. I then read the second book in the series in 2 days and now I'm reading the third! I like that Max is a kid genius. There's a lot of girl power!
