In the wake of their last adventure, Stephanie, Catherine, Jordan, and Justin find out their friend Special Agent Carleson has been suspended from the FBI. He’s accused of endangering the Math Kids, and if he’s found guilty, he could lose his job!

As the quartet tries to find ways to help Agent Carleson, trouble brews at school. In her new role as math club president, Catherine wants to lead the club to the state championship. But when their first preliminary competition goes awry and a strange note appears in her locker, she begins to suspect there’s a saboteur on the team.

The Math Kids must divide their attention between saving Agent Carleson’s job and saving math club. If they fail, both their math competition dreams and their future with the FBI will be at risk.
