Checkmate: The Killer's Game - Checkmate, #1

Notorious serial killer Damien Furr always has a plan. Typically, it's a plan involving bloodshed, murder, and vengeance. But, now, it also involves saving the world from the army of supernatural entities that want to see it destroyed. The last thing his plan requires is help. After hunting Damien for three years, Detective Drake Marshier never imagined that he'd have to work with the man he labored so hard to catch.
All he wants is to see the madman exactly where he belongs: rotting behind bars. But when the world is at stake, he may have no choice but to put old hatreds aside and fight for the greater good.
