With hand-colored photos of grave children holding, sitting on, or clambering over rocks, Christian (Chocolate, A Glacier Grizzly, 1997) poetically suggests picking up pebbles to see if they are skipping rocks or scraping rocks, wishing rocks or worry rocks, or perhaps just rocks with marvelous things in or under them. Lember (The Shell Book, 1997) adds muted but natural-looking tints to soften the lines in her woodsy, idyllic outdoor scenes. Like Meredith Hooper's Pebble in My Pocket (not reviewed), this suggests to children the rewards of taking closer looks at these most commonplace of natural objects. (Picture book. 6-8)
