Query: Amazing short stories

This is an amazing collection of short stories, that fills in gaps in the immortal Prydain Chronicles. Among the stories are the chilling story of Spiral Castle and the sword Dyrnwyn, a story of crime and horrific punishment, and the story of Angharad, Eilonwy's mother, who defied tradition and orders for true love. Also, the backstory for the three hags in the Marshes of Morva, the book of Three, and the foundling Dallben. A must-see for Prydain fans.
