John Rain: Paradox Code (Kindle Worlds Novella)

John Rain sees ghosts. He's been seeing them a long time. But now, they're coming from his future, not his past. And one of them is his killer.

What do you do when you're just a regular working class assassin and you get hired to take out your own killer?

If you're John Rain, and your best friend is a vampire, you make the guy sorry he ever thought about taking you out.
