In his first-ever collaboration, 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. An earthquake in Israel reveals a tomb buried in the heart of the mountain. A trio of investigators—a military forensic expert, a Vatican priest; and a brilliant but disillusioned archaeologist—are sent to explore the macabre discovery, a subterranean temple holding the crucified body of a mummified girl. James Rollins is the New York Times bestselling author of international thrillers, translated into more than forty languages. His Sigma series has been lauded as one of the "top crowd pleasers" and one of the "hottest summer reads." In each novel Rollins unveils unseen worlds, scientific breakthroughs, and historical secrets. Says Rollins, "The Blood Gospel came about from viewing Rembrandt’s painting 'The Raising of Lazarus.' It struck me strange how scared everyone looked, and this started me down a road of reflection about early Catholicism, vampirism, and a story began to unfold. I knew this could be a huge, ground-breaking new mythology, a story so epic in scope that I knew I didn’t want to tackle this alone." Rebecca Cantrell's Hannah Vogel mystery novels have won the Bruce Alexander and Macavity awards and been nominated for numerous others. She and her husband and son just left Hawaii's sunny shores for adventures in Berlin.
