This is literally one of my favorite books ever! (And I've read a lot of books.) It was so interesting and when I was done with the first one I really wanted the second one. It was easy vocabulary - wise, but otherwise, really, really, really, good!

This book surprised me a lot. It was a fun story with exciting action and I didn't know what would happen unlike most books.

I really love this book! I already want the rest of the series! I would definitely recommend this book to anyone who likes science, saving the planet, and/or books about loneliness and friendship.

I think the book was ok because I like Albert Einstein but it was not very "good story".

AMAZING GREAT BOOK
