From the back cover:
Evangeline Walton is the author of Prince of Annwn, The Children of Llyr, The Song of Rhiannon and The Island of the Mighty - each a branch of the epic Welsh book of mythology, The Mabinogion.
The Saturday Review said about her work: "These books are not only the best fantasies of the 20th century, but also great works of fiction. They are actual retellings of the diverse legends of The Mabinogion in novel form...dealing with Good and Evil...and the nature of love."
