It's Brains vs. Brawn in a Battle to Rule the School! Packed with action, suspense, and memorable characters, this witty school story is perfect for fans of page-turning adventures. Got a problem? Head upstairs to Mac's office — located in the fourth bathroom stall — and he and his best friend, Vince, will solve it...for a small fee. These sixth-grade problem-solvers have always been able to fix anything, but they might have finally met their match. It turns out that the legendary teenage bully Staples has expanded his high school gambling operation to Mac's grade school. He's fixing games, beating up students, and even threatening to kill their pets. To put a stop to Staples and his gang, Mac is going to need the help of a wannabe spy, a graffiti ninja, and nine of the biggest bullies in school. Will his crazy scheme work?
