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

AMAZING GREAT BOOK

I love the idea that kids can do anything

Great story. Really fun. I want the other books.

It's ok. It's... a good plot albeit VERY unrealistic VERY weird and also I personally didn't like it that much. I did finish it and read it again, but it's still only 'ok' in my opinion.
