A winning wheel of cheddar with braggadocio to match narrates a tale of comeuppance and redemption.From humble beginnings among kitchen curds living "quiet lives of pasteurization," the Big Cheese longs to be the best and builds success and renown based on proven skills and dependable results: "I stuck to the things I was good at." When newcomer Wedge moves to the village of Curds-on-Whey, the Cheese's star status wobbles and falls. Turns out that quiet, modest Wedge is also multitalented. At the annual Cheese-cathlon, Wedge bests six-time winner Cheese in every event, from the footrace and chess to hat making and bread buttering. A disappointed Cheese throws a full-blown tantrum before arriving at a moment of truth: Self-calming, conscious breathing permits deep relief that losing-even badly-does not result in disaster. A debrief with Wedge "that wasn't all about me" leads to further realizations: Losing builds empathy for others; obsession with winning obscures "the joy of participating." The chastened cheddar learns to reserve bragging for lifting up friends, because anyone can be the Big Cheese. More didactic and less pun-rich than previous entries in the Food Group series, this outing nevertheless couples a cheerful refrain with pithy life lessons that hit home. Oswald's detailed, comical illustrations continue to provide laughs, including a spot with Cheese onstage doing a "CHED" talk.From curds to riches, from meltdown to uplift-this multicourse romp delivers.
