When a centuries-old map inked with human blood resurfaces at an elite auction in Venice, it ignites a deadly chain of obsession, murder, and revelation. The map known only as Mappa Sanguinea is said to chart a path to relics beyond imagination. But those who follow its lines never return whole... if they return at all.
Disgraced detective Evander Holt knows myths don't kill people, but the night the map is stolen and its new owner dies screaming, his skepticism drowns in blood. As the same vein-like markings begin to spread beneath his skin, Holt realizes the artifact isn't a treasure; it's alive, and it's using him to finish what it started centuries ago.
From the catacombs of Saint Corbin's Abbey to the drowned tunnels under Venice, from Crete's sunken monasteries to the shadowed catacombs of Jerusalem, Holt and historian Julia Vale race to uncover the truth before the map redraws the world in blood.
But some paths were meant never to be traced, and some secrets demand more than life as payment.
A masterful blend of history, horror, and heart-stopping suspense, Blood Map is a gothic treasure hunt through faith, greed, and the endless hunger of what should never have been found.
Every drop points the way.
