Dare you enter the stone circle? The world’s most unlikely ghost-busting duo—actress Diana and handsome young bishop Alistair—are back in this spine-tingling paranormal mystery from New York Times bestselling British fantasy author.

There are stories about the dilapidated stone circle at Chipping Amesbury, going back centuries. Of people going missing, never to be seen again. Of people found dead inside the circle. Of monsters, and of demons.

The villagers may tell the tales with relish to visiting tourists, but a careful observer will notice that there is no transport to the stone circles, no tours on offer, and the locals stay well away.

Alistair Kincaid, the youngest–ever bishop of All Souls Hollow, is an expert in Britain’s ancient stone circles. That’s why, when landowner Sir Neville Chumley announces his plans to restore the circle to its ancient glory, he agrees to take part in a documentary about the project.

Well—that, plus talented actress Diana Hunt is on board. Ever since their last encounter, when the pair of them hunted ghosts and solved a murder, the tabloids have dubbed them the Holy Terrors, and Alistair can’t wait see her again.

But soon after filming begins, Alistair and Diana are plunged into a terrifying mystery. For the repositioning of the final stone unleashes a series of blood-chilling events that threaten to make them both believe in demons—if, that is, they make it out of the stone circle alive.
