Question: The Owl Service is a low fantasy novel for young adults by what English novelist, best known for his children's fantasy novels and his retellings of traditional British folk tales?
Context: Wildwood: The Wildwood Chronicles, Book 1 is a 2011 children's fantasy novel by The Decemberists' singer-songwriter Colin Meloy, illustrated by his wife Carson Ellis.  The 541 page novel, inspired by classic fantasy novels and folk tales, is the story of two seventh-graders who are drawn into a hidden, magical forest, while trying to rescue a baby kidnapped by crows.  They get caught up in an epic struggle, and learn of their connection to a magical parallel world while confronting adult authorities who are often cowardly or dishonest.  The natural beauty and local color of Portland, Oregon figure prominently in the book. The Owl Service is a low fantasy novel for young adults by Alan Garner, published by Collins in 1967.  Set in modern Wales, it is an adaptation of the story of the mythical Welsh woman Blodeuwedd, an "expression of the myth" in the author's words. Victoria Strauss (born in 1955, in Exeter, New Hampshire) is the author of nine fantasy novels for adults and young adults, including the "Stone" series ("The Arm of the Stone" and "The Garden of the Stone") and the "Way of Arata" series ("The Burning Land" and "The Awakened City").  She has written hundreds of book reviews for magazines and ezines, including SF Site and "Fantasy" magazine, and her articles on writing have appeared in "Writer's Digest" and elsewhere.  In 2006, she served as a judge for the World Fantasy Awards. Rosemary Sutcliff CBE (14 December 1920 – 23 July 1992) was an English novelist best known for children's books, especially historical fiction and retellings of myths and legends.  Although she was primarily a children's author, the quality and depth of her writing also appeals to adults.  In a 1986 interview she said, "I would claim that my books are for children of all ages, from nine to ninety."  Some of her novels were specifically written for adults. Adam Leonard is an English singer-songwriter working mainly in the folk, psychedelic and electronic music fields.  His style is often described as lo-fi and the subject matter of his songs somewhat unconventional.  Since his debut album 'How Music Sounds' in 2003, he has released many EPs, albums and mini-albums on various small labels.  Live performances, which have so far been limited to the UK (Manchester, London and Northern Ireland) are as intriguing as they are rare.  In 2008 he opened for British folk legend Steve Ashley.  He regularly collaborates with other musicians, most notably Pat Gubler (P.G. Six), Ashley Cooke (Pulco), Gareth Davies, and Steven Collins of The Owl Service, a band for which Leonard provided vocals for their 2010 album 'The View From A Hill'.  At the close of 2010, a limited edition album entitled 'Nature Recordings' was released on vinyl only by the London label The Great Pop Supplement.  In 2011 Leonard provided the soundtrack to Claudia Heindel's award-winning independent film Lucky Seven.  In 2012, Nature Recordings was issued on CD by Manchester-based label The Northwestern Series. The Changeover: a Supernatural Romance is a low fantasy novel for young adults by Margaret Mahy, published in 1984 by J. M. Dent in the U.K.  It is set in Christchurch in the author's native New Zealand. The Paladin is a 1988 fantasy novel by science fiction and fantasy author C. J. Cherryh.  It was published by Baen Books and was nominated for the Locus Award for Best Fantasy Novel in 1989.  The book features no actual magic or supernatural occurrences, and as such it can be considered an example of the low fantasy subgenre of fantasy fiction.  It takes place in a fictional country clearly modeled upon (but by no means identical with) China of the Tang Dynasty. Liege & Lief is the fourth album by the English folk rock band Fairport Convention.  It is the third and final album the group released in the UK in 1969, all of which prominently feature Sandy Denny as lead female vocalist (Denny did not appear on the group's 1968 debut album).  It is also the very first Fairport album on which all songs have either been adapted (freely) from traditional British and Celtic folk material (for example "Matty Groves", "Tam Lin"), or else are original compositions (such as "Come All Ye", "Crazy Man Michael") written and performed in a similar style.  By introducing songs of this genre into the group's repertoire Denny, who had previously sung and recorded traditional folk songs as a solo artist, was instrumental in this transformation.  Although Denny quit the band even before the album's release, Fairport Convention has continued to the present day to make music almost exclusively within the traditional British folk music idiom, and are still most strongly associated with it. Lloyd Chudley Alexander (January 30, 1924 – May 17, 2007) was an American author of more than forty books, primarily fantasy novels for children and young adults.  His most famous work is "The Chronicles of Prydain", a series of five high fantasy novels whose conclusion, "The High King", was awarded the 1969 Newbery Medal for excellence in American children's literature.  He won U.S. National Book Awards in 1971 and 1982. Alan Garner OBE (born 17 October 1934) is an English novelist best known for his children's fantasy novels and his retellings of traditional British folk tales.  Much of his work is firmly rooted in the landscape, history and folklore of his native county of Cheshire, North West England, being set in the region and making use of the native Cheshire dialect.
