Fearing that he may be failing fourth grade, Hank enlists the help of his friends, and even his annoying younger sister, in an effort to prevent his parents from attending a parent-teacher conference. 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.
