A myth needs to be changed and re-arrangedA blocking stone ~ placed by a Christian Priest in ancient times ~ is affecting the magical powers of the ley lines, under the earth on the Hill of Tara.To visit the stone passageway and time portal through the cruciform chamber of New Grange forces Maya and Dan to revisit previous lifetimes.Maya returns to her former lifetime as Dierdre (from the myth of Dierdre of the Sorrows) who learns she will be forced to marry King Conchobar of Ulster who seeks to possess her beauty.Yet only the mystical supernatural beings, who are the Tuatha de Danann, will be able to change the myth which has gone down into history for Dierdre.Ultimately she, in her turn ~ together with Dan who has to revisit the Cauldron of Dagda, re-find the spear, the sword and the stone of the Lia Fail ~ must help them in their quest to free Ireland from the blocking stone in the present century.
