“Only rarely does a book make your jaw drop. Tom Grace’s The Secret Cardinal is such a novel. It is as riveting as it is shocking and revelatory. Here is a story of corruption, politics, murder…all tangled around a secret war waged in the most surprising place of all: behind the walls of the Vatican. A political and religious tour-de-force that should be read by everyone.”

–James Rollins, New York Times bestselling author of The Judas Strain
