Book 5 of the Pendragon Cycle. A magnificent epic set against the backcloth of Roman Britain and Celtic legend. 'Only that which endures beyond time is worth having. Well I know it. I, who have given all for the mastery of time and the elements, know the value of life. Not for nothing am I called the Queen of Air and Darkness.' An old enemy arises, and Arthur's dreams of establishing his Summer Realm of peace and prosperity face ruin when the sacred relic, the Holy Grail, vanishes as the result of a hideous betrayal. So now Arthur faces the greatest challenge of his sovereignty: a quest of recovery and a trail that winds inexorably toward a grim confrontation with his most foul nemesis… and his destiny.
