Anything by Chris Grabenstein is great, although most of his books are for advanced readers this book is for typical and advanced readers alike. If you like action plot twist and lots of science this book is for you.
I have read this book over and over! It is amazing!
This book is by far one of my favorite ones!
I really enjoyed this book, and was also very excited to find out that it is part of a series!
This book is so awesome! I love how the book transports me into the story! I had so much fun reading and thought it was cool to read about Max solving problems around the world! I highly recommend this book and believe me, you will love the book too!
