Accidental Exorcist by Daniel Falicki

3.54

Fate has dealt Richard Vanuck a very strange hand; he's a natural born exorcist. In fact, he's the best there's ever been, and with possessions on the rise across the city he's booked solid. Eventually he comes to realize that performing exorcisms is the only thing he's truly good at, even though his daily battles with Satanic forces are wearing him down.
