Frank Einstein and the Bio-Action Gizmo (Frank Einstein Series #5): Book Five Hardcover – Illustrated, 17 October 2017

My kid loves this series....

These books sparked my 7 year old's love of reading! He's now read the whole series. These were a great way to get my science and math kiddo interested in literature!

Good book

I purchased for my 7 year old grandson and he loved this series. He likes them so much he read them twice.

It was a hit with my son! He is expecting the last one to be released. And this comes from a boy who barely read 2 or 3 books the whole 2016. He now has read every book of the series

My son devours these books. Such a fun series.
