The pressure is on when Hank Zipzer is chosen as pitcher for the softball team at Public School 87's annual Olympiad, the most anticipated day of the school year. Inspired by the true life experiences of Henry Winkler, aka The Fonz, whose undiagnosed dyslexia made him a classic childhood underachiever, the Hank Zipzer series is about the high-spirited and funny adventures of a boy with learning differences.
