Shine a light into the unknown There are still dark corners of our planet that are yet to be explored. In this remarkable book, Steve Backshall offers an unflinching account of his adventures into these uncharted territories around the globe, in search of world firsts. Each location brings its own epic challenges - whether it's the first climb of an arctic ice fall in Greenland, the first recorded navigation of a South American river, or the first exploration of the world’s longest cave system in Mexico. But all of them represent new tests of the limits of human endeavour. Accompanying a major 10-part series on BBC and Dave, Expedition is a breathtaking journey into the unknown, and a brilliantly written celebration of the pleasures of genuine discovery.
