The Celts are one of the world's most mysterious ancient people. In this compelling account, Alice Roberts takes us on a journey across Europe, uncovering the truth about this engimatic tribe: their origins, their treasure and their enduring legacy today. What emerges is not a wild people, but a highly sophisticated tribal culture that influenced the ancient world - and even Rome. It is the story of a multicultural civilization, linked by a common language. It is the story of how ideas travelled in prehistory, how technology and art spread across the continent. It is the story of a five-hundred year fight between two civilizations that came to define the world we live in today. It is the story of a culture that changed Europe forever. “Roberts's lightness of touch is joyous, and celebratory” -  Observer “Clear-spoken and enthusiastic” - Telegraph
