Follow Jenna, Caleb, and Ari as they embark on their newest time travel adventure in Terra Tempo: The Four Corners of Time. When Ari discovers a time map of the Colorado Plateau, he and the twins find themselves on a fast paced journey from Earth’s underwater beginnings to the steamy jungles and huge creatures of the creepy Cretaceous. But this time, there is more at stake than just survival. This time, they are not alone. Join the intrepid trio as they venture into prehistoric life on Earth – they must find ways to protect their map and all of the precious resources that the map reveals, or the rest is prehistory!

“This entry in the series finds Jenna, Caleb, and Ari with a new time map of the Colorado Plateau in Arizona, home of the Grand Canyon. It can take them back in time more than 500 million years. The children are drawn in an expressive cartoon style, while the depictions of nature are detailed, realistic, and richly colored. There is a great deal of scientific and historical information in the story, but it is conveyed through rather stilted, expository dialogue, with no additional end materials. In between, however, are vicious dinosaur battles, attacks from giant amphibious fish, and attempts by other time travelers to steal the time map. Children, especially those with an interest in prehistoric life, may be too engaged by the lively time-travel story line to mind a little didacticism.”

“Imagine Herge has written ‘Look & Learn,’ if he’d allowed Tin Tin to become the central figure in that magazine, and later on, compendium, if he’d been allowed to do that and had been guided by a think tank of geologists, botanists, paleontologists, and pulp adventure writers, then the finished product, that would have been the ‘The Four Corners of Time.’”
