"I have traveled south from Stornoway through all the Hebrides to Ulster, to Galloway, to the Isle of Man, southern and western Ireland. I can report that there is such a place as Celtic Britain, that it shares a common culture, an intimately related history and strikingly similar geography. The story of Celtic Britain can be found in these places."

Alistair Moffat's journey, from the Scottish islands and Scotland, to the English coast, Wales, Cornwall and Ireland, ignores national boundaries to reveal the rich fabric of culture and history of Celtic Britain which still survives today. This is a vividly told, dramatic and enlightening account of the oral history, legends and battles of a people whose past stretches back many hundred of years. The Sea Kingdoms is a story of great tragedies, ancient myths and spectacular beauty.
