Pink-haired goth Tiff Cordero isn't a witch. She's a clairaliant, someone who smells spirits. And she's been hired to sniff out a ghost who has recently started to give migraines to the patrons of a local coffee shop.

Only problem: nobody's died anywhere near the building recently, no one has cursed the place, and the only odor Tiff can pick up is the smell of burnt plastic.

If she can't solve the case, all the cool patrons will ditch the coffee shop—and it's already in a neighborhood getting updated and plasticized out of existence.
