In this book for 4 to 8 year-olds two young dinosaurs outwit a fearsome T. Rex. Jos (a young Triceratops) and Ski (a young Pteranodon) live in the Ancient Steamy Jungle. They meet and become friends. They explore the jungle together looking for food, other friendly young dinosaurs, and perhaps adventures. They encounter a large and fierce Tyrannosaurus, known as the Great Dinosaur of the North. He is looking for prey and gives chase. Ski stays on the ground with her friend Jose and distracts Rex (as the young dinosaurs call him). She finds a way for both the young dinosaurs to escape to safety and be ready for more adventures.
