From Chris Rylander, author of the breakout hit Fourth Stall saga, comes an incredibly funny and clever mash-up of middle grade school story and spy adventure.

There are places in the world where heroes are born. There are places where brave men and women fight a never-ending battle against evil in order to keep our country and all other countries safe. There are places where the fate of our planet is being decided, even at this very moment, the consequences of which will echo through history.

None of these places is in North Dakota.

Carson Fender, seventh grader and notorious prankster, knows this. He's lived in North Dakota for his entire life, going to the same boring school every day, the same boring movie theater every week, the same boring state fair every year. Nothing ever changes, and nothing ever happens. That is, until today. Because today a desperate man hands him a package with a dire set of instructions. And that package is going to lead Carson to discover that there's a secret government agency operating in his small, quiet North Dakota hometown. And that this agency needs his help.

Editorial Reviews

From School Library Journal

Gr 6–8—Carson is a perpetually bored seventh grader who satisfies his craving for action by orchestrating increasingly elaborate pranks at school. One day, he is handed a mysterious package and told he must deliver it—but not open it under any circumstances!—and suddenly life becomes anything but boring. The package is connected to a top-secret government agency, which recruits Carson to protect one of his classmates and foil the plans of a terrorist organization. Excitement builds as Carson—codename Zero—and his quirky friends put together the puzzle as only a team of plucky, imaginative kids can. Carson and his friends are funny and likable, and the pacing of the story is just right. The action steadily builds to a climax that satisfies, yet also whets the appetite for a sequel. Good for reluctant readers, and for any kid who likes tales of action, mischief, and friendship.—Emma Burkhart, Springside School, Philadelphia, PA

From Booklist

Seventh-grader Carson Fender pulls pranks to liven up the most boring school in the most boring city in the most boring state. But when a stranger gives him a mysterious package, Carson discovers that there is a supersecret government agency in town, and it wants his help. That plot produces an initially fast-paced and energetic story, and although part of the book’s appeal is its humor, it can fall flat at times. The supporting cast is a bit one-dimensional but entertaining. The mysterious-package countdown gives a lot of tension to the first part of the story, which then slows toward the end. But now that the series has a setup, further adventures should be able to move forward; enough dangling threads remain to support what comes next. Grades 4-7. --Peggy Hailey

My son loved this book. He's not a big reader, but said this was a good one. He wants book two and that is a big endorsement.

My son really doesn't like fantasy--he says that the only magic is physics. If you have a similarly minded young person, this book might make them happier than Harry Potter.
