Miles Murphy and Niles Sparks are great at being terrible. Their pranks bring joy to their classmates and embarrassment to their nemesis: blowhard Principal Barkin. But one day, a scheme goes too far, and Principal Barkin ends up fired. The new principal (who is also named Principal Barkin) runs the school with an iron fist, out to destroy all signs of fun.
Miles Murphy is known for one thing and one thing only: pranking. He’s the best prankster his school has ever seen. So when he’s forced to move to boring Yawnee Valley (also known for one thing and one thing only: cows), he assumes he’ll be the best prankster at his new school too. There’s one problem. The school already has a prankster — a good one. A really good one.
