An Ancient Strife (Caledonia #2) by Michael Phillips

Andrew Trentham's personal pilgrimage to discover his heritage takes him to Scotland. Tracing his roots through the kilted Highlander whose portrait hangs in the Trentham family home, Andrew's quest for meaning climaxes in the fields of Bannockburn, where the ancient strife for freedom was waged by the mighty Robert Bruce. Will Andrew gain the courage and vision he needs from the great king's example? Andrew Trenham's personal odyssey to Scotland heats up when he meets a fiery Scottish woman and becomes enmeshed in the investigation of a missing gemstone.
