Excalibur Parchment, The

A mythical sword.
A sinister force.
A quest that crosses centuries in a battle for global power.
The spine-tingling plotlines of two centuries of intrigue converge in the search for a powerful icon whose ownership could mean the difference between life and death for thousands, especially travel writer Stone Wallace and his mentor, Professor Huw Griffiths, whose daughter becomes a pawn in the fight to save a way of life, the church, and the concept of freedom.
Stone is plunged into a labyrinth of deceit, murder, and kidnappings as he races against time to find the mythical Excalibur, King Arthur's sword of legend. He sprints from Washington to Venice and London, winding up in a little known corner of Wales. As Stone seeks to save his friends, he battles Druids, the modern revival of a hate-inspired pagan group. Already they have killed and destabilized governments in pursuit of their secret agenda, and they're willing to sacrifice anyone who stands in their way. In the United States, one of their own is perilously close to becoming President.
Following clues left by a twelfth-century Welsh monk who also fought to save the sword, Stone finds they have much in common. Both doubt their ability to fulfill their quests, and both battle enemies who want to kill them and destroy all organized religion, especially Christianity.
Excalibur is the key.
