a graphic novel by Abby Howard
Ronnie is just a normal fifth-grader trying to pass her science class's impossible quiz on the history of dinosaurs . . . until she happens upon her neighbor--Ms. Lernin--a retired paleontologist. With the assistance of Science Magic, Ronnie and Ms. Lernin travel back through time and space to experience the Mesozoic Era firsthand. They visit three important time periods in the development of the Mesozoic Era: the Triassic, the Jurassic, and the Cretaceous. Along the way, Ronnie finds herself face-to-face with real-life dinosaurs and reptiles, like stegosauruses, velociraptors, and thalattosaurs. With the help of her neighbor's trusty knowledge of prehistoric times, she learns the differences between herbivores, carnivores, and omnivores, as well as between dinosaurs, insects, and reptiles. This insightful and informative graphic novel uses engaging art to bring facts to life, giving kids the tools to understand the evolution of these prehistoric creatures and the important effects this era had on our world today.

Sandy and Dennys have always been the normal, run-of-the-mill ones in the extraodinary Murry family. They garden, make an occasional A in school, and play baseball. Nothing especially interesting has happened to the twins until they accidentally interrupt their father's experiment. Then the two boys are thrown across time and space. They find themselves alone in the desert, where, if they believe in unicorns, they can find unicorns, and whether they believe or not, mammoths and manticores will find them. The twins are rescued by Japheth, a man from the nearby oasis, but before he can bring them to safety, Dennys gets lost. Each boy is quickly embroiled in the conflicts of this time and place, whose populations includes winged seraphim, a few stray mythic beasts, perilous and beautiful Nephilim, and small, long lived humans who consider Sandy and Dennys giants. The boys find they have more to do in the oasis than simply getting themselves home--they have to reunite an estranged father and son, but it won't be easy, especially when the son is named Noah and he's about to start building a boat in the desert.
