Magician trilogy

Gifts from Gwyn's grandmother on his ninth birthday open up a whole new world to him, as he discovers he has magical powers that help him heal the breach with his father that has existed ever since his sister's mysterious disappearance four years before.

Gwyn Griffiths draws on the strength of his namesake and ancestor in Welsh magic, Gwydion Gwyn, in an effort to purge the anger from an ancient Welsh demonic god that he had helped release, and to soothe a moody, troubled soldier.
