Cade Crowley, Demon Hunter (Cade Crowley, Demon Hunter Series #1‪)‬

Demons are dangerous things. They inflame your insecurities, turn your weaknesses against you, and whisper their thoughts into your ears in the darkness.

The Vatican wants them locked up, or banished back to Hell. Short on priests and long on money, they’ve had to resort to paying bounties to keep things under control. That means looking outside of the faithful, to mercenaries like Cade Crowley.

That’s not his real name, but then, it never is. A drunk, and a gambler, and a womanizer, Cade’s steeped in sin himself, but he has one advantage: the sight. He can see demons, and he can see spirits, and that means he can fight them, so long as he can keep his own demons under control.

But the Vatican doesn’t have the war between good and evil to itself, not anymore. Other religions want in, and they’re recruiting bounty hunters of their own. Some have faith, and some just have bills to pay, but all of them want Cade’s bounties for themselves.

Cade Crowley, Demon Hunter #1 (Short Story):

One of the Church’s faithful has summoned something up from Hell, to try to make a deal. But he forgot the first rule of the dark arts: don’t call on something you don’t know how to control. He’s trapped in his own summoning circle, and the only one who can get him out is Cade.

Cade Crowley, Demon Hunter is a short story, and is the first in the series.
