Jack Montfort grew up in the shadow of Glastonbury Tor in a town revered as the mythical burial place of King Arthur, and, according to New Age followers, a source of strong druid power. Montfort has little more than a passing interest in the history of the area - until he comes across an extraordinary chronicle almost a thousand years old . . .

For something terrible and bloody shattered Glastonbury Abbey's peace long ago - and now it is about to spark a violence that will reach forward into the present . . .
