I loved this book so much! It was super duper cool because it was adventurous and mysterious and just fun! And I like the drawings because they look like a sketch someone drew on notebook paper. I recommend this book!

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!
