The Guardians of Petra

The dead don't leave forwarding addresses. But sometimes they leave maps. Thirteen months after the accident that took his wife, a grieving archaeologist has traded the dig sites of Egypt for a quiet porch in Connecticut and the company of her old dog, Scarlett. Then a headline cuts through the fog: beneath the Treasury at Petra, workers have uncovered twelve skeletons arranged in a perfect circle - and at their center, a single ceramic cup.
He has seen that cup before. It is sketched in the back pages of Lydia's last notebook, beside a coordinate for a chamber that shouldn't have been found for another year. She wasn't guessing. She was following a map no one else could read - the Babylonian Cipher - and what she traced in the margins of the royal records points to something the world was never meant to dig up. They are calling it the find of the century.
A chalice that gives back the dead. For a man who has buried the one person he could not live without, it is the most dangerous promise ever made. Because something has been guarding that cup for a very long time - and something else has been waiting for a man desperate enough to drink from it. The Guardians of Petra is a supernatural archaeological thriller about grief, temptation, and the difference between the cup that empties a man and the Cup that was poured out.
A standalone novel in the Unseen Truth series, in the tradition of Frank Peretti and Ted Dekker. The greatest battles are the ones no one sees.
