She was Eilan, the daughter of a Druidic warleader and gifted with visions. In a land struggling to survive both Roman conquerors and her own people's enemies, surely fate had marked her to become a priestess of the Forest House.

But first Eilan had chosen a different, forbidden path - to love Gaius, a soldier of mixed blood among the legions sent to subdue her country. So she must hide a terrible secret when she is anointed as the new High Priestess. With mighty enemies poised to usurp the wealth of magic the Forest House sheltered, Eilan could only trust in the power of the great Goddess to find her destiny amidst the treacherous labyrinth in which fate had placed her.

Through the generations the women of Avalon prepare for the coming of the Defender, the sacred king who will guard the old ways of the Britons and save their land from destruction. On the holy isle of Avalon, hidden in the mists between the world of Faerie and the world of men, they wait. For High Priestess Caillean, facing the Roman foe, salvation comes not through victory, but bitter sacrifice.

Two hundred years later, her successor, Dierna, faces a new enemy: the Saxon hordes who assail her people like savages. By the time of Viviane, Britain seems wholly lost. But a Merlin is made amongst the Druids once more, and the day of the Defender, who will come to be known as Arthur, draws close.

A spellbinding historical fantasy, Lady of Avalon links the best-selling novels in the Avalon series - The Forests of Avalon and The Mists of Avalon.

In this epic work, Bradley follows the arc of the timeless tale from the perspective of its previously marginalized female characters: Celtic priestess Morgaine, Gwenhwyfar, and High Priestess Viviane.

Then Helena's son, Constantine, becomes Emperor, and her position as Empress-Mother propels her to prominence at a crucial turning point in Western history. Seeking a way to bridge the pagan world of the Goddess and the new Christian Empire, Helena embarks on a pilgrimage to the Holy Land to find the truth that transcends both the old religion and the new.
