The Waters of Life 

It is 290 AD. The Islands of Orkney are Pictish and pagan and ruled by rival Cènels or clans grouped in certain ancient sites.

One clan seeks dominance and tries to use their powerful sorceress to take control leaving the weaker clan reeling, with their queen in mortal danger.

Can they break the almost impossible spell set upon them. Will the hero Gallan overcome the forces set against him?
