The concluding novel in the Guenevere series.
In the serene heart of Camelot, Guenevere and Arthur are High King and Queen of a land at peace, as they prepare to celebrate the knighthood of Mordred. Arthur's son and heir, Mordred promises to be a worthy addition to the Round Table, and Guenevere has long forgiven Arthur for the adultery that brought him into the world.
But deep in his underground cave, Merlin has heard of a new threat to Arthur's peace. To the delight of the Christians, ancient enemies of all that Guenevere holds dear, the long-lost Holy Grail has come to light, together with word of a mysterious child who must find it to fulfil his destiny.
Other enemies from the past are stirring too. When the knights of the Round Table depart on the quest for the Holy Grail, leaving Arthur and Mordred behind, Morgan le Fay broods on her lifelong revenge, and knows the time has come.
As the shadows darken around Arthur and the band of knights, Guenevere counts on the love of her own knight, Sir Lancelot of the Lake. But when Lancelot's loyalty is called into question just as her enemies become strong enough to strike, Guenevere faces the spectre of a dual betrayal . . .
