I really liked this book because it teaches you to not give up on good opportunities although that is not what Max Enstien did.

I really liked this book! Lots of funny stuff and it makes one realize that the planet is kinda in trouble if the CMI does not exist.

This is another one of the best books I've read. It is exciting and very suspenseful. A long book with short chapters (which I like😊) and I love the secret agencys and kid teamwork. I would definetely recommend.

It wasn't to long or to short. I loved it so much that I'm reading it for the third time!

This was a great book. I enjoyed the humor, the suspense and the hero is very likeable.
