"The time of the angels may have passed for now, but they will return." The Archangel Michael defeated the Devil in Helston and cast him into Hell forever. This legend is retold every spring at Helston's Flora Day. But the legend is about to become a reality. Underground in the rocks and sea-caves of Cornwall, Lucifer is stirring. Soon he will wake and break free. And this time he will prevail against his old adversary Michael. Verity is entranced by a beautiful stranger she meets on the cliffs. The young man cannot tell her who he is or where he is from. Unbeknown to her, Lucifer is bringing her under his spell. Verity's friends fall away from her, frightened by her obsession, and she finds herself alone when a cosmic battle is fought in the skies of Cornwall. The future of all mankind is at stake.
