Eighth Moon Bridge

'They say he brought back some Spanish gold and others say he didn't bring anything except the rags he was wearing but had the power to turn stone into gold and that the two stories somehow got mixed up.'
Did Olghair MacKenzie steal alchemical secrets from the Egyptians? Or was he a rebel pirate who found refuge on a small Scottish island after the Armada? Does his treasure still lie hidden there?
Six hundred years after MacKenzie's death, an ex-footballer returns to the island where he spent his youth. As the first frosts of winter arrive, Jack moves into a fisherman's cottage fragrant with the scent of the sea. After many restless years, it is a true homecoming. Delighting in his employment as postie, he starts to reconnect with himself, with his family and with this tiny community.
The tale of Olghair MacKenzie has fascinated Jack since childhood and he resolves to discover the truth behind the legend. To do so, he must unlock the secret of a bridge the shape of a perfect wave, understand the significance of stone number 759 and find out what is meant by the eighth moon. Can Jack trust the dreams of the local seer, or grasp the clue in the old Gaelic way of counting the months?
Jack's quest is truly magical, for it will lead him into very personal territory, unveiling links that tied him to the island long before he ever set foot there.
