It is 20,000 BC and the Earth is in the grip of a bitter ice age. Massive ice sheets cover much of northern Europe, Asia and America. You are the chief of a small clan of humans that lives on the tundra-a frozen region of dry grassland that lies between the ice sheets in the north and forest in the south. Only mosses, lichens, grasses and low-lying shrubs can grow on this windswept land. Winter is approaching, and the great herds of reindeer that roam the area are moving south to find food. They feed on lichens and grasses which are covered by snow during the winter months. Your clan relies on reindeer to survive. Their meat is your main food and your clothes and shelters are made from their thick, warm hides. You also use reindeer antlers and bones to make tools and weapons. To survive the winter, you must therefore follow the reindeer on their long migration. Can you lead your clan on this dangerous journey and bring them safely back to your camp on the tundra when summer, and the reindeer, return?
