Tuuli knows there's a bigger world out there, and when she spots a strange boy lurking outside their camp, she realises that he might hold the adventure she is looking for.

He is from another tribe, sent to find safer ground and as he and Tuuli strike up an unlikely friendship, they set out on a journey that will impact the rest of human history.

A vast adventure with a very human heart, full of wild animals, huge scenery and heart-stopping danger and inspired by real anthropological discoveries.
