An exciting adventure from a masterful storyteller set at the beginning of the twelfth century on the Island of Lewis in the Outer Hebrides, off the west coast of Scotland.The Eye of Callanish tells the story of a young girl, Mairi, who is persecuted for being in league with the Devil. She believes that she is able to communicate with the ancient people who built the temple of Tall Stones at Callanish, and that they have given her a beautiful white horse.Mairi is aided in her escape from her persecutors by Neil and the hermit Brother Durston, who we first met in Weapons of the Wolfhound. Together they seek for the truth.Who are these ancient people? Are they from the West - the legendary land Saint Brendan had sailed to in the sixth century, the Vinland of the Vikings, the North America of the present day? Where did the white horse come from? And who is the dead body in the cleft?This is the story of being at once fascinated by the search for Truth... and at the same time terrified of it...
