PreS-K—Free an excitable beastie in a library and shelves will fall, pages will rip, and books will be chewed. After a fun, but slightly wild ride through the different sections of the building, Tess sees the need to get T. rex back into his book. But can she do it without saying goodbye forever? Luckily, she has the rules fresh in her mind, and the skills to keep a dinosaur in check. When reading Tess and T. rex's story, the roars, snarls, and snorts will need to be delivered in full force. Youngsters can also use their stern parental voice to say "Watch out!" "Time out!" and "Be careful!" and give commands like "Charge on" and "Yee-haw!" Buzzeo and Yoshikawa make it obvious how children are supposed to behave in a library while giving sneak peeks at some of the different sections and exciting possibilities that they might encounter on a visit. Mixed-media illustrations have loud colors, quick movements, and costume changes to match the section of the library. Although this book is lively at the start, it does have a calm ending consisting of a hug and a whisper. Offer this one to children who enjoy Jane Yolen's "How Do Dinosaurs…" series (Scholastic).—Tanya Boudreau, Cold Lake Public Library, AB, Canada
