"These four fantasy-fiction books by American author Evangeline Walton (The Prince of Annwn, The Children of Llyr, The Song of Rhiannon and The Island of The Mighty) are based on traditional Welsh myths. Someone sent them to me back in 1978 because I’d written a song called Rhiannon 5 years earlier. Walton started her work around 1934 and finished in 1974, which was right around the time that I wrote Rhiannon, so I felt like when her work ended, mine began."
