I decided to make a grading system for the books I review. Let me know what you think :) I might change it around a little, but for right now I will see how it works.
In the book, there are 4 kids who become a team of spies that infiltrate a school to stop a principal from trying to rule the world by sending hidden messages to people through tv and radio. They need to find out how he is doing it and stop him before time runs out. Along the way the kids have to learn to trust each other and work together as a team even when working alone sounds so much easier.
The book has humor and suspense and is an all around great read. It definitely gets five stars.
If you like the book, I heard that it is the first in a series.
