Joanna Kavenna went north in search of the Atlantis of the Arctic, the mythical land of Thule. Seen once by an Ancient Greek explorer and never found again, mysterious Thule came to represent the vast and empty spaces of the north. Fascinated for many years by Arctic places, Kavenna decided to travel through the lands that have been called Thule, from Shetland to Iceland, Norway, Estonia, and Greenland. On her journey, she found traces of earlier writers and travellers, all compelled by the idea of a land called Thule: Richard Francis Burton, William Morris, Anthony Trollope, as well as the Norwegian Polar explorer Fridtjof Nansen. She met wilderness-lovers; poets writing epics about ice; Inuit musicians and Polar scientists trying to understand the silent snows. But she came to discover that a darkness also inhabits Thule: the Thule Society, obsessed with the purity of the Nordic peoples; the 'war children' - the surviving progeny of Nazi attempts to foster an Aryan race; as well as ice-bound relics of the Cold War.
