Guenevere ...Last in a line of proud queens elected to rule the fertile lands of the West, true owner of the legendary Round Table, guardian of the Great Goddess herself . . . a woman whose story has never been told — until nowBrokenhearted at her parting from Lancelot and anguished over the loss of the sacred Hallows of the Goddess, Queen Guenevere reconciles with Arthur, although the fragile bond between them is threatened by a new presence at Camelot. Prince Mordred, Arthur's son by Morgan Le Fay, has come to stay and to be proclaimed heir to Guenevere and Arthur's kingdoms. Arthur has even designated for his son the Siege Perilous, the one unoccupied seat at the Round Table — the seat reserved for "the Son of the Most Peerless Knight in All the World."But at the knighting, when Mordred takes his seat, the great Round Table, owned by the Queens of the Summer Country since time immemorial, cracks down the center. A terrible darkness falls over Camelot and in the midst of the chaos appears a new knight, Sir Galahad. Barely fourteen, he may hold the key to the mystery of the stolen Hallows, which the Christians believe to be the Holy Grail. The scene sets into motion the final brilliant cycle of the Arthurian legend-the Quest for the Grail and the fall of Camelot-which brings Guenevere to the brink of the most dreaded tragedy of all . . . and may ultimately complete her destiny as the greatest and most powerful Queen of the Isles.
