With THE BLOOD GOSPEL, James Rollins and Rebecca Cantrell combined science, myth and religion to introduce a breathtaking world where miracles hold new meaning and the fight for good over evil is far more complicated than we ever dreamed. And now, in this epic conclusion to the Order of the Sanguines trilogy, they take us to the very pit of Hell itself, making us peer into the abyss and face our greatest fears, to answer the ultimate question: What price will we pay for true salvation?

While exploring a tomb hidden for centuries in the depths of Masada, Israel, brilliant archaeologist Erin Granger began an incredible journey to recover a miraculous ancient artifact tied to Christ himself. In this follow-up to THE BLOOD GOSPEL, an attack outside Stanford University thrusts Erin back into the fold of the Sanguines. As the threat of Armageddon looms, she must unite with an ancient evil to halt the plans of a man determined to see the world end, a man known only as Iscariot.

In his first-ever collaboration, New York Times bestselling author James Rollins combines his skill for cutting-edge science and historical mystery with award-winning novelist Rebecca Cantrell's talent for haunting suspense and sensual atmosphere in a gothic tale about an ancient order and the hunt for a miraculous book known only as The Blood Gospel.
