Love Among the Ruins by Warwick Deeping

Trumpets were blowing in Avalon of the Twelve Towers, echoing through the valley where the sun shone upon the woods, the sere leaves glittering like golden byzants as they fell. The sky was a clear canopy, drawn as blue silk from height to height, tenting the green meadows. Avalon's towers rose black and strong above the sheen of her quiet waters.

From Gambrevault came the Lord Flavian to claim his wife once more. Through the brief days of autumn Aurelius of Gilderoy had decreed him an exile from the Isle of Orchards, pleading for the girl's frail breath and her lily soul that might fade if set too soon in the noon of love. In Gambrevault the Lord Flavian had moped like a prisoned falcon, listening to the far cry of the war, hungry for the touch of a woman's hand. Modred had snatched the Madonna of the Pine Forest from burning Gilderoy. She had been throned at last above the tides of violence and wrong.
