★ "Innerst’s moody acrylic, colored pencil, and ink illustrations create dynamic, expressionistic scenes that dance across the page like musical notes. Expository spreads show Sondheim making music or working in the theater, but it’s the conceptual illustrations that will intrigue creative readers: Sondheim riding a roller coaster with relevant terms ('melodious score,' 'lyrics that soar!') placed along the rails or surrounded by oversize puzzle pieces posing questions such as 'What is the sound for loneliness?' and 'Should the first and last notes rise?' Indeed, puzzles prove an inspired central metaphor for the creative process as Sondheim perfects his work. Frankel’s lilting rhyme gives the verse a pleasing cadence for reading aloud without following a consistent rhyming scheme, mirroring the ebb and flow of Sondheim’s own process. A brilliant glimpse at a musical genius, imbued with a profound truth: Creativity is truly about the journey."—Kirkus Reviews, starred review

★ "An emphasis on the considerations involved in composing—some written on the puzzle pieces that appear frequently in the illustrations (“How does the character feel?” “Do the words bounce with the music?”)—help make the subject accessible to readers who may not yet be familiar with Sondheim’s work. Fanciful art in acrylic, colored pencil, and ink in Innerst’s (illustrator recently of Joan Mitchell Paints a Symphony, rev. 5/25) recognizable style incorporates musical notes, images of the composer at work, and references to his musicals; see especially a spread whose puzzle pieces evoke Georges Seurat and thus Sunday in the Park with George. A focused introduction to Sondheim for budding young creatives."—The Horn Book
