King's Arrow by Douglas Bond
Agnus M'Kethe, a ready archer, guards sheep from scavenging crows. Loyal to his family, Agnus must match wits in a life-and death struggle against Highlanders. By faith, Agnus 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's true test of manhood and marksmanship will come at the Battle of Drumclog.
The Crown and 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. Recommended for ages 10 to 14.
