The Golden Strangers by Henry Treece

This novel is set in the period in which Stonehenge was built. It tells the story of the invasion of the Southern chalk country of Britain by the Golden Strangers, the men of the Sun from across the seas who come in search of fresh pastures. The invaders are turned back from the Village on the Hill, Craig Dun, by Garroch, the young Chieftain of the primitive and terror-ridden community.

But his triumph is short-lived, for he falls under the sensual spell of Isca, the golden-haired princess who rides with the invaders.

Set at a vital cross-roads in history, this is the story of a young Prince of the dawn world, his henchmen and his woman. It shows the triumph of the fair-haired nomads from the North, with their savage worship of the sun and their bardic tradition, over the small dark Neolithic men of the South—the Iberians.
