Michael Pye's The Edge of the World is an epic adventure: from the Vikings to the Enlightenment, from barbaric outpost to global centre, it tells the amazing story of northern Europe's transformation by sea. 'An utterly beguiling journey into the dark ages of the north sea. A complete revelation . . . Pye writes like a dream. Magnificent' Jerry Brotton, author of A History of the World in Twelve Maps This is a story of saints and spies, of fishermen and pirates, traders and marauders - and of how their wild and daring journeys across the North Sea built the world we know. When the Roman Empire retreated, northern Europe was a barbarian outpost at the very edge of everything. A thousand years later, it was the heart of global empires and the home of science, art, enlightenment and money.
