Prince of Annwn
Prince of Annwn is a fantasy novel by American writer Evangeline Walton, the first in a series of four based on the Welsh Mabinogion. The novel is a retelling of the story of the First Branch of the Mabinogion, Pwyll Pendefig Dyfed (Pwyll, Prince of Dyfed), and hence is chronologically the first of Walton's Mabinogion novels, though published last.
