Persona Non Grata is growing, slowly but surely. Here's a quick list of places you can get it, as of 2/25/2013:
Directly from the Junkture.com store:
SIGNED paperback copy
Kindle edition
Nook/iBook edition
If you're in the Chicago area, go by this awesome store and get a print copy in person. You'll be supporting me by buying my book and also supporting a wonderful local business.
