Many scores of books about St Kilda have been published since Martin Martin's which appeared in the 1690s. Each one adds a little to our understanding of the community's origins, language, livelihood and continuous struggle to survive. All fascinating stuff! As a World Heritage Site, St Kilda's fame has steadily grown and is now of interest to hundreds of thousands worldwide. This latest book, describing the non-human population of the archepelago, is authoritatively written and beautifully illustrated. It adds enormously to our understanding of the way in which natural history is interwoven with the lifestyle and culture of the people. Highly commended.
