Wordless picture books require that readers dig deeply into the illustrations and their own imaginations to complete the story, and Lehman, author of Museum Trip, The Red Book, and others, is a master of the genre. In Rainstorm, the author deftly captures the emotion of a restless, lonely day stretching out to infinity, the fraught excitement of a good mystery, and finally the simple joy of discovering new friends, all without a single word. Her precise and colorful illustrations complement the book’s subtly surreal story.
