Rock tells his sensational, sometimes harrowing, sometimes hilarious, geological tale to a group of eager students.

– 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.
