1191 A.D. The orphan Tristan has joined the Knights Templar as a squire, journeying with Richard the Lionheart on his crusade to free the Holy Land from the Saracens. As defeat looms near, Tristan is entrusted with the most sacred of Christian relics, the Holy Grail. He must return it safely to Britain, but he must also keep it secret, because the Grail's power will drive men to madness, and even his fellow Knights Templar will kill for it.

Tristan teams up with the fiery Robard Hode— returning to his home in Sherwood after serving with the King's Archers—and Maryam, an equally fierce girl and a member of the dreaded Hashshashin. Together they must escape the Holy Land, dodging bandits, the forces of the Saladin, and unscrupulous knights who will stop at nothing to possess the Grail.
