Blood of the Templars(2004)

The order is ancient. The secret is eternal. The battle for the Holy Grail has begun.

Blood of the Templars is a series following David, an 18-year-old raised by monks who believes his parents died in infancy. When a fight at a party reveals he possesses extraordinary abilities—superhuman strength and rapid wound healing—David attracts the attention of the Priory of Sion and the Knights Templar. Both ancient orders recognize him as the key to locating the Holy Grail, thrusting the teenager into a quest that will reshape everything he thought he knew about his past. As David navigates his newfound powers and the dangerous world of secret societies, he must uncover the truth about his origins while staying ahead of those who would exploit his connection to history's most coveted relic.
