A Night In Annwn by Owen Jones

William Jones, a sheep farmer from the Brecon Beacons, had led a happy life, until his wife, Sarah, died young. It left him devastated and seemingly bent on self-destruction. His daughter, Becky tried to help, but even she was losing patience with her father.
One evening, he is certain that he has died and been put out of his misery, but it was not to be. He recovered. However his life was never to be the same again.
He had discovered Annwn where his wife lived, and his newly found vitality changed his life and that of all those with whom he came into contact.
