An ancient secret. A dangerous hunt. A race against time.

Archaeologist Dr. Laura Stevens leads an expedition beneath the Temple Mount, searching for traces of a forgotten past. What she uncovers could rewrite history: ancient documents from the Knights Templar that point the way to the Holy Grail - an artifact promising power, knowledge, and even immortality.

But Laura's discovery attracts powerful enemies. The NSA deploys cutting-edge technology to track her every move, the Vatican weaves its own shadowy web of intrigue, and a ruthless Army special unit closes in on her team. From the jungles of Africa to the misty valleys of England, Laura must risk everything to protect the Grail from those who would abuse its power.

Yet the true Guardians of the Grail are watching - and they will stop at nothing to keep its secret safe.

The hunt begins. Who can you trust when the powers of the world align against you?
