The Grail Delusion

It is twenty years since Hengest and his warriors were driven from Britannia by Aurelius Ambrosius. Now Childric, his kinsman, hungers for revenge and the reconquest of what he calls Angleland. Yet one obstacle stands in his path: Merlin.

To strike at Arthur’s greatest ally, Childric turns to the Angle wise woman, Morwei, who conjures the illusion of the Holy Grail—a lure designed to ensnare Merlin and lead Arthur’s marchogion to ruin. But can even such a deception undo the most sagacious of wizards?

Note that, though the book is a sequel to the English Dawn Pentalogy, the story is complete in itself.
