Prince of Annwn by Evangeline Walton

Evangeline Walton first wrote the MABINOGION TETRALOGY in the late 1930s and early 1940s. Only the fourth book in the sequence was published at the time, under the title The Virgin and the Swine. The series was rediscovered in the early 1970s; The Virgin and the Swine was reprinted as The Island of the Mighty, and the other three books saw publication for the first time. Prince of Annwn is the first in the sequence but was the last to be published.
