Lucy M. Boston (1892–1990), born Lucy Maria Wood, was an English novelist who wrote for children and adults, publishing her work entirely after the age of 60. She is best known for her "Green Knowe" series: six low fantasy children's novels published by Faber between 1954 and 1976. The setting is Green Knowe, an old country manor house based on Boston's Cambridgeshire home at Hemingford Grey. For the fourth book in the series, A Stranger at Green Knowe (1961), she won the annual Carnegie Medal from the Library Association, recognising the year's best children's book by a British subject. During her long life, she distinguished herself as a writer, mainly of children’s books, and as the creator of a magical garden. She was also an accomplished artist who had studied drawing and painting in Vienna, and a needlewoman who produced a series of patchworks.
