Two like plague and cholera. If there's one thing Miles Murphy excels at, it's playing pranks, causing mischief, and tricking people. There's no doubt: he is the best trickster his old school has ever seen. When Miles is forced to move to the boring backwater of Yawnee Valley, he assumes he will be the best trickster at his new school as well. There's just one problem: the school already has a trickster. And he's good—incredibly good! Miles is horrified to see that his rival is like a phantom: no one knows him, and his pranks never get exposed! When Miles discovers that the teacher's pet Niles is behind the genius pranks, the biggest trickster competition Yawnee Valley has ever seen unfolds.
