This book is really funny. The jokes are based on science, math, engineering, and technology. The author is a kid. I really liked the activities included. I made the hagfish slime.

This book is the 4th book in the series. I have read most of them. It's my second favorite in the entire series (next to Spy Camp) and has lots of action and drama. I hope others will enjoy this book as much as I did.

This book is very cool and interesting. It has a unique concept about how living in space isn't as fun as it is in space movies like in Star Trek or Star Wars. it may not have as much action as the other book series from Stuart Gibbs that I'm reading called Spy School, which can make the book a little boring at times. I still enjoyed it nonetheless.
