Heretic

An epic historical saga steeped in myth and legend, Heretic brings history to life with the wonderful characters and heart-stopping battle scenes that have made Bernard Cornwell a New York Times bestselling novelist.
Thomas of Hookton is a young man but already a seasoned veteran of King Edward's army. His fearlessness and uncanny prowess with the longbow make him a natural leader in what will be remembered as the Hundred Years' War. But the dangers on the battlefield are small compared to those of his true quest -- a hunt for a mysterious relic rumored to be the Holy Grail. Accompanied by a small but able band of soldiers, Thomas travels to his ancestral home, only to find it ensnared in a murderous struggle for possession of the Grail. But it is the arrival of a mortal foe -- and the rumored discovery of the Grail itself -- that forces Thomas to make a choice of historic consequence.
