Britain has a single pod of orca, also known as killer whales, native to its home waters, although other orca visit from more northern regions. In 2014 Dr Natalie Sanders joined the crew of the HV Silurian to seek them out and study them before we lose them forever. In The Last Sunset in the West she discusses them one by one, and the many issues surrounding their lives in a captivating account that will take the reader deep into the history of our relations with the sentient and beautiful creatures.
