The Great Ice Age (Hardcover)

The early history of our planet, and the weird and wonderful creatures that inhabit it, are endlessly fascinating subjects. In this series the prehistoric world is explored at first hand by travellers in a space-time shuttle. Mike and Helen travel backwards in time to explore the world as it was in prehistoric times, accompanied by Jen, their space-time ranger, and Timcom, their computer. Each book takes them to a different time period and involves them in a variety of adventures. This particular book looks at the time of the great Ice Age and the changes that occurred at this time.
