Shadow Curse by Jack Hampton

Jake Rogers, full-time grad student and haunted artifact collector in my spare time. That’s right, I’m a collector–even when that means collecting artifacts someone else currently owns.

I used to be a Sentinel, but after what happened to my brother, I just don’t have it in me anymore to monitor all the paranormal beings of the Underworld.

But then the killings start. Killings that shouldn’t be possible. Now the Police are on my case to solve the case before the magical murderer strikes again and reveals the Underworld to all the unsuspecting humans.

On top of it all, ghosts suddenly seem to have made it their sole mission to turn me into one.

Unfortunately for them, I’ve just ordered a few ice-cold cans of Whoop-Ass–and these phantoms are looking awful thirsty.
