Remember the Icarochenis? How about the Gaslodon? Don’t worry; neither does anyone else. In Flip-O-Storic, the heads, bodies, and tails of ten actual prehistoric beasts—the popular woolly mammoth and saber-tooth tiger among them—may be exchanged to allow readers to make up their own imaginary, exotic species. There’s no formal story, but each panel describes its accompanying illustration, comprising one third of a creature. About Nia we learn: “I’m very agile, which helps me outmaneuver predators. Watch out! I can also deliver a powerful kick with my hind legs.” Ball’s lively, colorful illustrations will attract curious readers aged four and up.
