Sutcliff was Carnegie runner-up again for her retelling of the Arthurian legend in "Tristan and Iseult", which in 1971 won the American Horn Book Award. In 1985, "The Mark of the Horse Lord" was the inaugural winner of the Phoenix Award, created by the Children's Literature Association to recognise the best English-language children's book that did not win a major award when originally published twenty years earlier. It is named for the mythical bird phoenix, which is reborn from its ashes, to suggest the book's rise from obscurity. "The Shining Company" won the same award in 2010.
