Blurb from the first edition (1981)

Driven by the sinister forces of his own heritage, Brennis Gehan Fifth, Lord of Valdoe, is planning the genocide of the nomadic tribes who impede the spread of his empire in the land that was southern England of 5,000 years ago. With his army swelled by foreign mercenaries he prepares to march through the snows to annihilate the nomads' retreat in their winter camp.

Word of the Lord of Valdoe's intentions has already reached the nomads, but when their chieftain is killed in a hunting accident it seems his successor will not heed the warning. In all the tribes, only Tagart understands the danger and is strong enough to face the Flint Lord, but first he must win the strange battle for leadership, waged according to ancient and ruthless laws. The campaign that he then inspires is a superb story of desperate courage.

This novel of intrigue, violence and betrayal in the land of our Stone Age forefathers is a magnificent successor to the author's The Stone Arrow. Here, spurring the Flint Lord's drive for conquest, is his passion for his beautiful, decadent sister, a drive and a passion which lead inexorably to catastrophic consequences.
