Sent to explore a subterranean temple revealed after a devastating earthquake in Israel, a trio of experts discover the mummified remains of a crucified girl. But as they excavate, a brutal attack sets them on the run and they’re thrust in to a race to recover what was once preserved in the sarcophagus. A book rumoured to have been written by Christ’s own hand.

Hunted by a force of ancient evil, Dr Erin Granger and her two sons must follow the trail back thousands of years, to a time when ungodly beasts hunted the dark spaces of the world. And here they stumble across a secret sect within the Vatican, one whose existence was painted by Rembrandt himself. A shadowy order known simply as The Sanguines.
