Can you spot a fake? Brady Hart knows the truth: He's not a normal sixth-grade boy. Armed with a keen sense of justice and a photographic memory, he's on a mission to sniff out bad guys and use God's wisdom to set things right in the world. If he can figure out how. After all, he's just a kid. His best buddy, Sunday from Kenya, keeps him calm and laughing most of the time. Gladiss Finkel annoys him, but she has his back. That's a hard fact to ignore, since she always shows up wherever there's trouble, including Colby's department store right as he's about to bust a shoplifter. Brady can't ignore something else. Counterfeits are popping up everywhere. Headphones with a tweaked logo, a sneaky store manager, and even a new leader at church--suddenly nothing adds up, yet everything fits together. Brady decides it's time to strap on his Belt of Truth (the one he made out of aluminum foil in third grade), call in Special Agent Max Dunham from the FBI, and uncover the lies threatening to destroy the people he loves.
