Modern Sorcery by Gary Jonas

Death by dark magic

As soon as I get over my ex, her father hacks her mother apart with a sword.

She hires me to prove dark magic was involved. Hey, it’s what I do as a paranormal investigator, so I get why she thinks I can help.

But my secretary, Esther, a ghost from the 1920s flapper era, and Kelly Chan, my magically engineered protector, are dead-set against me getting involved. With all the deadly magic flying around, they may have a point.

Because the sad truth is, I don’t have any magic of my own.
