From the introduction:
It was all going according to plan...
Occult Chicago. Beneath the surface there are movers and shakers, magics and artifacts, all hidden from mortal eyes. There’s so much right there for the taking-money, power, fame, respect-it feels like all you need to is just reach out and grab it. And that’s just what you intend to do. You’ve got supernatural powers, a foolproof plan, and then? Easy street. What could go wrong?
...But then Harry Dresden showed up.
This playset has a special twist-Harry Dresden is the Tilt. One way or another, Harry gets involved in the action, which in turn leads to the characters’ plans going awry (if they weren’t heading off the rails already).
