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.
