From 1964-70, the author Roger Perry served as the Director of the Charles Darwin Research Station on the Galapagos Islands, the famously isolated archipelago on which Darwin based his groundbreaking studies that unlocked the secrets of the origin of species. During the six years he worked there, Perry travelled extensively around the remote cluster of islands, assessing the status of its giant tortoises and other wildlife, and helping to establish the national park that attracts thousands of visitors each year. Perry and his wife then moved to Christmas Island, a lonely atoll notorious as a base for staging allied nuclear bomb tests. One of the author's many tasks was to ensure that the islanders and the millions of sea birds that made the island their home, could co-exist in harmony. Following his years in the Pacific, Perry became Administrator of Tristan da Cunha, where he found the inhabitants struggling to come to terms with modern life while retaining many of their age-old traditions and customs.
