When historian Julien Moreau is found dead at the top of Magdala Tower, his body marked with ancient sigils and a relic clutched in his frozen hands, the past erupts into the present.
Disgraced detective Lucien Vail, haunted by loss and visions he can’t explain, is drawn into a ritualistic web of murder, secrets, and blood-soaked prophecy. With the help of symbologist Eva Chevalier, whose family vanished chasing the same mystery, Lucien races to decipher a trail of arcane clues left in the margins of a forbidden codex.
From forgotten crypts beneath Rennes-le-Château to mountain abbeys where the dead still whisper, the pair must uncover the truth behind the Codex Tenebris—a manuscript said to reveal the final resting place of the Grail. But they are not the only ones seeking it.
The Watchers move in silence. The Resurrectors kill in the name of revelation. And the Grail is no salvation. It is a curse.
Ancient forces are waking. And death is just the beginning.
