Levison Wood's epic 2600-mile journey - across the mighty Caucasus mountain range on the tense frontier between Europe and Asia - continues. The explorer and his guide journey by any means available deeper into the badlands of Dagestan, a Russian Republic that the British Foreign Office warns against visiting under any circumstances. Unperturbed, the intrepid explorers embrace the open hospitality of the region's warrior clans, discover the stunning beauty of a land that few westerners have seen, and take a perilous horse trek to the ancient city of Derbent, accompanied by an armed guide to protect them from wolves and bears. Entering Azerbaijan, Levison is joined by a new guide, Namin, to accompany him through this country of extraordinary contrasts: of extreme wealth and subsistence poverty; and of steel-and-glass modernity and almost biblical ancient settlements.
