It was a great book.

This book is one of the best books ever! Definitely read it. It is full of adventure, and surprises! You will never guess what will happen next. Totally read this!

I really like this author and I was so happy when this book hit pjourway! So I chose it immediately! I was not disappointing! It's a really good book for people who like science and Albert Einstein!
