Tristan da Cunha is both a remote group of volcanic islands in the south Atlantic Ocean and the main island of that group. It is the most remote inhabited archipelago in the world, lying approximately 1,511 miles (2,432 km) off the coast of Cape Town in South Africa, 1,343 miles (2,161 km) from Saint Helena and 2,166 miles (3,486 km) off the coast from the Falkland Islands. The territory consists of the main island, Tristan da Cunha, which has a diameter of roughly 11 km (6.8 mi) and an area of 98 sq km (38 sq mi), the smaller, uninhabited Nightingale Islands, and the wildlife reserves of Inaccessible Island and Gough Island. As of October 2018, the main island has 250 permanent inhabitants who all carry British Overseas Territories citizenship. The other islands are uninhabited, except for the personnel of a weather station on Gough Island. Tristan da Cunha is part of the British Overseas Territory of Saint Helena, Ascension, and Tristan da Cunha. This includes Saint Helena and also near-equatorial Ascension Island, which lies some 1,741 miles (2,802 km) to the north of Tristan. There is no airstrip of any kind on the main island, meaning that the only way of travelling in and out of Tristan is by boat, a six-day trip from South Africa. Angry Island: The Story of Tristan da Cunha (1506-1963) by Margaret Mackay was first published in 1963, the year the Tristanians returned to their island after its volcano erupted in 1961 and forced the evacuation of the entire population to England. As the most isolated inhabited island on Earth, the Tristanians have had to adapt and develop innovative ways in order to survive, and in this book, Mrs. Mackay tells a very detailed history of Tristan da Cunha since its discovery over five hundred years ago, sharing many shipwreck tales and early yet failed attempts to settle the island. A gripping read!
