Wikipedia, 31 Oct. 2012: "Lucy M. Boston (1892–1990) was an English novelist who wrote for children and adults, entirely after age sixty. She is best known for the 'Green Knowe' series, six low fantasy children's novels published by Faber from 1954 to 1976. Green Knowe is the setting, an old country house and manor based on Boston's Cambridgeshire home at the time. For its fourth book, A Stranger at Green Knowe (1961), she won the annual Carnegie Medal in Literature from the Library Association, recognizing the year's best children's book by a British subject."
