This was one of the best PJ library books I have ever read. I love science and it is really like sciencey (I made that word up) and you learn a lot about Albert Einstein. If this is not a choice and you want to read it, go to amazon.

I love this book so much, it's now a fav of mine! So awesome, and it's good for I'd say 9 and a half and up! I looove it!!

It's full of action, humour, and adventure! I thoroughly enjoyed reading this book, there wasn't even a hint of boredom in this book! Definitely recommend!

It's a really exciting book! There's a TON of action, and it's cool. The main character changes throughout the story, and the plot makes your heart race. It's an awesome book!

It was a bit dragged on...
