The Sinai Directive

In Egypt, those within the Saint Catherine Monastery are brutally attacked and a secret that has been hidden for more than 3,500 years is stolen.

In Zurich, an arms dealer makes an agreement with a band of elite terrorists for one-of-a-kind weapons of mass destruction, for a treasure that was presumed destroyed during the Exodus.

When a conversation between two men is covertly videotaped by an operator of the CIA, Vatican Intelligence and the Mossad realize that the partial message received was filled with enigmas. Having interpreted the data, the Vatican determines that the communication between these two men was a barter agreement that would place Israel within the crosshairs of the entire Middle East. That agreement: the Islamic State would exchange the relic of the golden calf for weapons of mass destruction.

With the possibility of bringing the world to the brink of war, the Vatican Knights are once again called to duty to search for the long-missing relic of biblical lore before the exchange can be made. However, the terrorist cell in search of the iconic piece is a faction that had been pieced together from elite forces throughout the Middle East. With Kimball Hayden leading his force of Vatican Knights, they will come up against the best warriors the Islamic State has to offer, in a race to find the golden calf.
