The Templar Chronicles 1 The Heretic

At the end of the First Crusade, the church created a monastic military order known as the Knights Templar. Now, rising up from the ashes of history, they are the Vatican's last defense in the war between good and evil.

AN ANCIENT ARMY REBORN
Cade Williams is no ordinary man. His ability to cross over to the other side makes him uniquely qualified to command the Churchs special operations division. As a modern-day Knight, Cade can use the curse that has scarred his soul as a weapon against the forces of darkness. But a new kind of unholy war is brewing and soon Cade may be the last man standing between the living and the dead.

AN ANCIENT MYSTERY RESURRECTED
The desecration of Templar cemeteries has sparked a full-scale investigation. Cade and his team suspect that a cabal of necromancers is behind it all. Their purpose: to claim the legendary powers of a lost holy relic for their own ungodly campaign. For Cade, there's only one way to stop them -  by tracking the dead himself, crossing the most sacred of battle lines and facing his own terrifying demons.
