The Hiraeth trilogy darkens. After their victorious battle in Wicklow, Mona disappears without a trace.
Despite months of searching, Cai is forced to face life without her and seeks happiness in a life far removed from his Welsh language and community.
Mona's dramatic return throws his life into chaos as she reveals the harrowing details of the past fifteen months at the hands of their true enemy.
With the Welsh and Irish Druids uniting behind them, Mona and Cai must stand together if they are to overcome the powerful and evil force to which their own destinies are fatally entwined.
A fast-moving, contemporary action story, `Hiraeth' is a trilogy inspired by the ancient Celtic texts of the Mabinogion and the Ulster Cycle.
The story has been woven into an epic power struggle, which straddles myth, Celtic identity and adventure.
