On the 11th of June in 1488, two armies meet in battle at Sauchieburn, near Stirling. One fights for King James the Third of Scotland, the other is loyal to his eldest son, Prince James, Duke of Rothesay. Soon, James the Third is dead, murdered as he flees the field. His army is routed. Among the dead is Sir Thomas Sempill of Ellestoun, Sheriff of Renfrew, whose son and heir, John, escapes with his life. Once John's career as knight and courtier seemed assured. But with the death of his king, his situation is fragile. He's the only surviving son of the Sempill line and he's unmarried. If he hopes to survive, John must try and win favour with the new king. And deal with the ruthless and powerful Lord Montgomerie. . .
