Sixth-grader Nate Fischer never wanted to be a spy. But when a mysterious phone call lands him at a new school, he realizes that he doesn't have a choice: his new school is a spy factory. He barely has time to learn his locker combination before his first mission plunges him into danger. A sinister organization is trying to destroy his school and take over the world, and Nate has only a few hours to stop the evil plot.
With just a backpack full of spy gadgets, a bit of spy training, and their own cunning to guide them, Nate and his partner Lucy follow a trail of secret messages in pursuit of the one thing that can save their school from destruction. As they are chased through subway tunnels and across rooftops, Nate and Lucy must race to complete their mission before it is too late. Cracking secret codes, evading capture, and battling enemy agents-sixth grade wasn't supposed to be like this!
