A must-purchase for nonfiction collections as rockhounds will delight in finding out how rocks are born. – School Library Journal, STARRED REVIEW * 6/1/25 *Rock explains with humorous yet informative visuals and snappy, personalized descriptions how it cycles through the three types of rock (igneous, sedimentary, and metamorphic) over time. Whether blasted from a volcano, thrown onto land by a tsunami, or kicked by dinosaurs, the seemingly boring life of a rock is anything but. – Booklist * 05/01/2025 *A rock … pipes up to retrace its own four-billion-year history. That the same rock can change repeatedly from one type to another may be the main lesson readers will absorb… though the note of self-affirmation toward the end (“I’m proud to say that I’m here, I’m me, and…I ROCK!”) will never go amiss. – Kirkus * 05/01/2025 *A stone-focused read that strikes a rich vein of fun. – Publishers Weekly * 3/17/2025 *
