Orphan of Destiny — Michael P. Spradlin

Tristan and his companions -- the fiery archer Robard Hode and the assassin maid Maryam -- have escaped to England. But tragedy has occurred to Tristan's beloved abbey while they were on the Third Crusade, and Robard's home in Sherwood Forest suffers under the rule of the Sheriff of Nottingham. Many obstacles still prevent them from delivering the Holy Grail into safe hands. Tristan must defeat the evil Sir Hugh in one final battle. And he must learn the secret of his birth, a secret Richard the Lionheart and Eleanor of Aquitaine are willing to kill to protect!
