As an escalating scourge of grisly murders sweeps the globe, archaeologist Erin Granger must decipher the truth behind an immortal prophecy foretold in the Blood Gospel, a tome written by Christ and lost for centuries. From the dusty shelves of the Vatican's secret archives to lost medieval laboratories, as clues are dug free from ancient underground chapels and found frozen in icy mountain caverns, Erin will discover that the only hope for victory lies in an impossible act-- one that will destroy not only her, but all she loves.
