In this final part of the Druids murder-mystery series, 6th century druid Gwynlan concludes his intriguing investigation into the murder of monks from the Celtic Church. With Rome's powerful allies on his heels, Gwynlan and his companions travel northwards from the sacred isle of Anglesey to the land of the enigmatic Picts. It becomes apparent that the talismanic fate of the Treasures of the Britons is closely entwined with the Picts' own inheritance. But far from being a land of myth and legend, this is a haven for the Cauldron of Rebirth, with an unexpected twist.
