Susan Mary Cooper (born 23 May 1935) is an English author of children's books. She is best known for The Dark Is Rising, a contemporary fantasy series set in England and Wales, which incorporates British mythology such as the Arthurian legends and Welsh folk heroes. For that work, in 2012 she won the lifetime Margaret A. Edwards Award from the American Library Association, recognizing her contribution to writing for teens. In the 1970s two of the five novels were named the year's best English-language book with an "authentic Welsh background" by the Welsh Books Council. Source: Wikipedia (en)
