Robert L. Harris was appointed to the warden service on Skellig Michael, County Kerry, Ireland, in 1987, where he has been managing the guiding system and monitoring the island for over thirty years. He has lived most of his life near the sea and on islands, and he has a great interest in both monastic and natural history. He spends May to October on Skellig Michael when the island is accessible, and in winter months lives at his home in County Leitrim with his wife, Maigread. Returning Light is his first book.
