The humorous adventures of an irresistible little rock who finds herself in constantly changing circumstances, Petra is a picture book that celebrates the power of perspective and believing in yourself. Petra is a little rock who believes she is a mighty mountain . . . until a dog fetches her for its owner, and she is tossed into a bird's nest. A mountain? No, Petra is now an egg! An egg of the world in a world of possibility. Until she's flung into a pond, and becomes an amazing island . . . and, eventually, a little girl's pet rock. What will she be tomorrow? Who knows? But she's a rock, and this is how she rolls! PreS-Gr 1—A rock imagines all the things she could be in this whimsical and uplifting story. Petra thinks of herself as a mountain, immovable and fearless—until a dog comes along and picks her up. Only then do readers learn that she is a rock. She is tossed into a nest and becomes an egg, and imagines grand possibilities there: she could be a dragon, a penguin, or even an amazing platypus. By the book's end, Petra, having become a multitude of different things, declares her plight to be "not bad at all" and wonders what she will become next. This story is a quiet lesson in perspective and finding the silver lining in situations beyond one's control. Petra is never short on optimism and only shows a bit of worry. The soft color palette creates a sense of calm, and Coppo has managed to create a rock with personality whose simple yet evocative expressions show both contentment and curiosity. Petra's motto, that there's no need to worry because she's a rock, and "this is how I roll," will resonate with many.
