The Electric Church (Avery Cates Series #1)

Avery Cates is a very bad man. Some might call him a criminal. He might even be a killer - for the Right Price. But right now, Avery Cates is scared. He's up against the Monks: cyborgs with human brains, enhanced robotic bodies, and a small arsenal of advanced weaponry. Their mission is to convert anyone and everyone to the Electric Church. But there is just one snag. Conversion means death.
