Young Duncan M'Kethe finds himself caught in the web of Sir James Turner, the former Covenanter turned military leader of the persecutors. Duncan is torn by his hatred of Turner's dragoons, who have treated his friends cruelly, and his father's instructions to love them. He must be true to Jesus Christ while attempting to rescue his father from enemy hands.

Angus M'Kethe, brave Duncan's younger brother, is no longer a child with a toy bow and arrow. He is now a young man, facing the same persecution and spiritual questions that his entire family has struggled against for years. Loyal to his family, Angus must match wits in a life-and-death struggle against Highlanders. By faith, Angus turns his beloved game of chess into a tool of victory. But desperate fear grips the Clan with an unexpected murder! Will Covenanters be found guilty? Angus' true test of manhood and marksmanship will come at the Battle of Drumclog! The Crown & Covenant series follows the lives of the M'Kethe family as they endure persecution in 17th–century Scotland, and later flee to colonial America. Douglas Bond weaves together fictional characters with historical figures from Scottish Covenanting history. "Douglas Bond in King's Arrow, once again will inspire boys to become men, and men to become men of God." R.C. Sproul Jr., Director, Highlands Study Center

The M'Kethe's team up again to stand for Crown & Covenant. Forced finally to fell to America, they must leave behind their most precious possession.
