Quick Assessment

A small boy slowly shrinks in this offbeat, surreal, and funny story, while the adults around him dismiss his experience as imagination or misbehavior. It gently explores feeling unseen by grown-ups, with mild classroom teasing and a trip to the principal's office, and is lighthearted throughout. Edward Gorey's pen-and-ink drawings give it an eerie, whimsical tone that suits children who enjoy nonsense and wordplay.
