Holy Grail history is full of stories that possess the power to seize the human imagination. These tales of quests and miracles, and of honor and betrayal, have captivated humankind for so long, say the authors of The Grail Code, because the stories really do touch the deepest parts of our hearts. They reveal our innate yearning to know Christ, to be in communion with the Divine. What we’ve lost in the pop-culture transformations of the Grail is what made it holy in the first place: the intimate link with the Eucharist.

The Grail Code by Mike Aquilina and Christopher Bailey is a literary and theological detective story, centuries in the making, that ends where Holy Grail history began—in the room where Jesus gathered his closest friends for the last time, spoke blessed words, broke bread, and shared a sacred cup.
