Zen and the Art of Faking It by Jordan Sonnenblick

SUMMARY: When eighth-grader San Lee moves to a new town and a new school for the umpteenth time, he doesn't try to make new friends or be a loner or play cool. Instead he sits back and devises a plan to be totally different. When he accidentally answers too many questions in World History on Zen (only because he just had Ancient Religions two schools ago) all heads turn and San has his answer: he's a Zen Master. And just when he thinks everyone (including the cute girl he can't stop thinking about) is on to him, everyone believes him . . . in a major Zen way.
